Bell Schedule
Developing the school bell schedule can be a very complex task especially
when incorporating shortened days for staff development, assembly schedules,
rotating schedules, block schedules, mandated testing schedules and final exam
schedules while at the same time keeping track of the total instructional minutes to
meet state and contractual requirements.
This tool is an Excel spreadsheet that automates the counting of the number
of instructional minutes and days in the school year. This allows you to be as creative as
you want and experiment with multiple bell schedules until you find the perfect one.
All of the formulas used in this spreadsheet are visible so you are able to learn how the
spreadsheet works, but be careful; if you delete a formula, the spreadsheet will not
work correctly. A basic understanding of Excel and working with formulas in Excel is
recommended to use this tool, but don’t worry, these instructions will provide you with
the basics of working with Excel and formula writing to get you started. So… let’s get
started!!
Click to proceed
When you first open the Bell Schedule spreadsheet, you will see the “Count Balance”
calculation area at the top left of the page

If you click on cell E1 (the one with the number 180) you will see this in the Formula Bar
Here is the formula - this is the typical structure of an Excel formula
=SUM(C18+C61+L61+R61+L19+R19+X61+X19+C103+L105+C143+L143)
Back
Click to proceed
We will get back to that formula in a minute. Let’s take a look at the structure
of formulas with a couple of examples:
1) Click on an empty cell somewhere on the spreadsheet – G10 would be a
good one to use
2) Enter an equal sign “=“ (no quotes) in the cell – typically, formulas in Excel
begin with an equal sign
3) After the equal sign, type in the number 180, then type the multiply sign
(the asterisk) and then type the number 360. Your formula should look like
this: =180*360
4) Then press Enter – did you get 64800? GREAT!!
This number (64800) is the number of instructional minutes per year currently (2013)
required by the state of California in public high schools. As you can see, this number is
used in cell E3 as a constant to evaluate the instructional minutes of the bell schedule you
create.
Let’s take a look at one more example…
Back
Click to proceed
1) Click on cell G10 and enter the number 180 (this will erase the formula you
entered in the previous example, but that is what we want to do
2) Click on cell G11 and enter the number 360
3) Click on cell G12 and enter the following formula: =G10*G11
4) Press the Enter key – Did you get 64800 again? GREAT!!
This method of entering formulas by referencing cells that contain constants instead of
imbedding constants within formulas is a far superior way of writing formulas – a lesson
that was clearly demonstrated at the turn of the millennium. You will see that this
preferred method is used throughout the Bell Schedule spreadsheet. (Go back and delete
your entries in cells G10, G11 and G12)
Getting back to the formula in cell E1:
=SUM(C18+C61+L61+R61+L19+R19+X61+X19+C103+L105+C143+L143)
The formula says to calculate the sum of the contents of the cells at C18, C61, L61, R61,
L19, R19, X61, X19, C103, L105, C143 and L143. Go to each of these cells on the
spreadsheet to see what’s there and check to see if the sum is correct. Did it add up to
180? GREAT!! Did you write the numbers on a piece of paper and add them up or did you
use your new formula writing skills in some blank cells on the Excel spreadsheet?? Either
way is fine!!
Now let’s get to bell scheduling!!

Getting Oriented
This is a reduced view of the
entire spreadsheet. You have
already seen the “Count Balance”
area on the top left.
The rest of the spreadsheet is
composed of 12 individual bell
schedule calculation areas. These bell
schedules are identical in format, but
differ in the use of time. For example,
schedule 1 is a traditional schedule,
the combination of schedules 2 and 3
make up an AB rotating block
schedule, add schedule 4 to this and
you can develop an AB block schedule
that banks time for a weekly, one-hour
staff development period. Let’s take a
closer look at bell schedule 1.

Minute Calculation
Formulas
These calculations are
used to compute time in
the bell schedule. The
1440 is the number of
minutes in one day. The
decimal fraction is the
number of minutes
entered for the length of
a component divided by
1440. This fraction is
used in the Bell Schedule
Section. I’m sure there is
a better way to do this,
but it is what I came up
with a long time ago and
it works.

Change the formula to read:
=SUM(E26:E40)-(E34)-(E29)
The Total Instructional Minutes
This is the formula that
calculates the total
instructional minutes in
cell E43:
=SUM(E26:E38)-(E34)-(E29)
This formula calculates the sum
of the numbers in the “E”
column from row 26 through 38
and then subtracts the numbers
in cell “E34” (Lunch) and “E29”
(Break) – minutes that don’t
usually count as instructional.
Notice that only 6 class periods
are included. What do you do if
you are on a 7 period day?
Adjust the formula in cell E43.

TOTAL INSTRUCTIONAL MINUTES

There are only 3 different formulas used
to produce the bell schedule: one that
copies the starting time of school, one
that copies the ending time of one
period to the next period’s start time
and one that adds the bell schedule
component minutes to the starting time.
Let’s take a look at these:
The formula in cell C24 is: =C10
All this does is make cell C24 equal to
whatever time is entered in cell C10 –
here the time 6:46 AM
The rest of the formulas in this column
all to the same thing – copy the ending
time of the previous period – here is
the formula in cell C27: =D26. Taking a
look at these two cells you will see the
same time – 8:47 AM

Now let’s take a look at the formulas that
really make this all work – in this example
the cells in column D, the “END” column,
cells 24 through 40. These are the cells that
add the bell schedule component minutes
from the Data Entry Section to the starting
time of the period. The formula in cell D24
is: =C24+E12
This takes the time entered in cell C24 (6:46
AM) and adds the minutes assigned to the
length of first period (57 minutes).
Remember – the formula uses the
calculation result in column “E”, not the
time entered in column “C”.
You don’t have this exact bell schedule
example in the Excel spreadsheet, but if
you look at the formulas in any of the
“END” columns, you can see how this all
works. By changing the column “E”
reference in the formula, you assign the
times listed in the Data Entry Section.

Did you notice when I showed you the
example of changing to a 9 period day that I
didn’t really finish the job? Well, let’s take
care of that now. This involves adding
formulas, which isn’t that big of a deal if you
just follow the pattern or copy formulas
DOWN. Let’s look at cell C41:
Remember, this column copies the
“END” time from the previous period.
You could just follow the pattern and
enter the following: =D40
This would copy the time of 3:54 PM
to cell C41. Another method would be
to select cell C40, click on “Copy”,
click on cell C41, click on “Paste” and
then press “Enter”. Both methods
work just fine. I prefer the copy and
paste method (with a slight variation)
and I’ll show you why on the next
slide.

Instead of copying and pasting
just one cell at a time, I prefer to
do it all at once. Start by selecting
all three cells that you need to
copy – in this example C40, D40
and E40. This is done by clicking
on cell C40, holding the click
down and dragging over cells D40
and E40, then releasing the click.
It should look like this:
Take note of this little
darkened square – next
we will use this to paste
down the formulas.

In Excel, the cursor normally looks something like this:
When you move the cursor on top of the little solid
square, it changes to look something like this:
While the cursor appears in this solid plus-sign mode, click and drag down to
cell E42 (for this example) and then release the click. This will copy DOWN the
“C” column formulas in the “C” column, the “D” column formulas in the “D”
column and the “E” column formulas in the “E” column. The formulas in the
“C” and “E” columns will be exactly what you want, but the formulas in the
“D” column will have to be adjusted. We will see why in the next slide.
Back
Click to proceed
When copying cells and pasting them in a new location (like we just did) Excel tries to
follow a pattern. Since the formulas in the columns “C” and “E” follow a pattern, these
cells are pasted in exactly like we want them. Since the formulas in the “D” column
reference various times in the Data Entry Section, these formulas need to be adjusted.
This is accomplished by looking at the Data Entry Section and finding the row with the
correct time element for the specific period and then changing the reference in the “D”
column. Let’s see how this looks:
REMINDER: Use THIS column of numbers for the formulas to calculate the END time of a
period.

TOTAL INSTRUCTIONAL MINUTES
377
This formula says: sum all the numbers from
cell E24 through E42 and subtract the
numbers in cell E34 and E29
This formula was set to
count the instructional
minutes before we added
periods to the day – so we
need to adjust the formula
to count the new periods.
The current formula is:
=SUM(E26:E38)-(E34)-(E29)
This formula starts counting
instructional minutes at
period 2 and ends at period
7 – a 6-period day. If you
want it to include all 9
periods, change E26 to E24
and change E38 to E42. The
new formula will look like
this:
=SUM(E24:E42)-(E34)-(E29)

Click to proceed
Using a combination of the 12 Bell Schedule Calculation areas in the spreadsheet and what
you have learned so far, you should be able to manipulate the schedules to come up with
the bell schedule you need. But there may be a need to add another row to a bell
schedule when there are no blank spaces to do this. No problem!!
1) Select the entire row where you need cells added
including the one cell to the left of the “PERIOD”
column (in this example cell A42). This needs to be
done to keep entries further down in this column
aligned properly
2) Click on Insert in the Task Bar and select Insert Cells
Back
3) This dialog box will appear asking how you
want the cells inserted – the “Shift cells
down” choice is what you want for this
example. Click on OK
Click to proceed
Now you have a blank row in the bell
schedule to add whatever you need
When you add cells like this, Excel
does a couple of very nice things
automatically for you. Notice that the
“TOTAL INSTRUCTIONAL MINUTES”
formula moves from cell E43 to cell
E44, but does the calculation include
the newly created row? YES!! The
formula changes it’s calculation range
to include the new row. (It also
adjusts any other calculations on the
spreadsheet that moved as a result of
the addition of cells) Another
automatic change is in the “Count
Balance” calculation area at the top
left of the spreadsheet. These
formulas are automatically changed
to account for the movement of cells.

A Word of Caution:
If you insert cells/move the location of cells on the
spreadsheet, make sure that the formulas at E1
and E4 of the “Count Balance” calculation area
contain the correct references to the cells on the
individual Bell Schedule that contain the number
of “Days on this schedule” and “Total Instructional
Minutes” (in this example – cell C18 for the “Days
on this schedule” and cell E44 for the “Total
Instructional Minutes”). When you add cells using
the above procedure, Excel takes care of the
formula adjustments, but I always check!
E44
The “Count Balance” calculation area is copied
below each of the 12 Bell Schedules for
convenience – you don’t have to go back to
the top of the spreadsheet to see the overall
effect of a change.
Click to proceed
Now you’re ready to start developing a complete bell schedule. We will begin with a
short example to create a rotating, A B block schedule.
When you first open the Bell Schedule
spreadsheet, it is set up with a fairly traditional
bell schedule that banks minutes for 4 days per
week and uses the banked minutes on one day
per week for staff development. It also contains
testing days and two different assembly days. The
complete bell schedule is made by combining
information from bell schedules 1, 5, 9, 10, 11 and
12. Take a look at these schedules to see how they
combine to make the complete bell schedule.
Back
Ok – now you want to get rid of this schedule to
make our example rotating, block A B schedule.
Be sure to work on a copy, just in case.
It’s very easy to get rid of this schedule – all you
have to do is delete the “Days on this schedule”
number on each of the schedules listed above.
These numbers are at cells C18, C61, C103, L105,
C143 and L143. Go to each of these cells and
delete the numbers in the cell (leave the cells
blank).
Click to proceed
The “Count Balance” calculation area should now look like this:
Now go over to Bell
Schedules 2 and 3 located
in the area from J7 to T32.
We will use these two
schedules to make our AB
block schedule.
Back
Click to proceed
Start with the Block Schedule A
We arbitrarily set the starting time of school to be 7:50 AM (any time can be used).
In the blank spaces of the “L”
column enter the following:
L11 – 86
L12 – 86
L13 – 86
L14 – 86
L15 – 5
L16 – 40
L17 – 10
L18 – 6
L19 - 90
The “L” column
will now look
like this
Back
Click to proceed
Now move to the Block Schedule B
In the blank spaces of the “R”
column enter the same
numbers you entered in the
Block Schedule A:
R11 – 86
R12 – 86
R13 – 86
R14 – 86
R15 – 5
R16 – 40
R17 – 10
R18 – 6
R19 - 90
The “R” column
will now look
like this
Back
Click to proceed
Now take a look at the “Count Balance” calculation area. You have a schedule with
180 days and exactly the required instructional minutes.
ALWAYS do a little checking to make sure!!
1) Are the “Days on this schedule” numbers at L19 and R19 included
in the formula at E1? (With E1 equal to 180 it is a good bet that
everything is OK.
2) Are the “Total Instructional Minutes” formulas at cells N43 and T43
calculating the correct minutes from the schedule?
3) Do you find (L19*N43) and (R19*T43) in the formula at cell E4?
Always perform these checks to make sure your
schedule is making the correct calculations.
Back
Click to proceed
Now for the final example, let’s get a bit more creative. You want to create an AB rotating,
block schedule, but you want to bank minutes so you can have one hour of staff
development time one day each week.
To do this, add in Bell Schedule 4. Try this on your own to see if you can come up with a
workable schedule. I will start you off with a hint:
Change the number of days on the A and B schedule to 75 each and set the number of
days on Bell Schedule 4 to 30. Now just enter times in column “X” and keep adjusting
times in columns “L”, “R” and “X” until you get a working solution.
Change to 75
Back
Set at 30
A working solution (one of many) is on the next 2 pages –
so you can either go ahead and see one solution or play
on your own to come up with one.
Click to proceed
These are the A and B schedules that bank time and would be in place 4 days per week.
