July 8, 2025

Still typing out employee schedules by hand or dragging cells like it’s 2005? Let’s fix that with an automated work schedule in Excel.

This guide will walk you through how to build a dynamic, colour-coded employee schedule that:

  • Automatically generates the dates for any month
  • Calculates finish times from standard hours and start times
  • Highlights days off, holidays, and sick days with drop-downs and colours
  • Summarizes days worked, sick, and on holiday
  • Looks good and saves hours each month

Of course, you can customize it to suit your unique requirements once you have the foundation.

Build a Smarter Work Schedule in Excel (That Updates Automatically)

Watch the video above for step-by-step instructions on how to build an automated work schedule, or follow the written instructions below.

Step 1: Generate the Dates for the Month

1. In cell B3, enter the start of the month (e.g., 1/7/2025 for 1st July).

2. In C5, enter the following formula to spill the dates across the row:

=SEQUENCE(1,EOMONTH(B3,0)-B3+1,B3)

3. Format the date cells:

  • Select the cells, press CTRL + 1 to open the Format Cells dialog.
  • Go to the Number tab → Custom.
  • Enter this custom format:
    d CTRL+J ddd
    (Press CTRL+J between the d and ddd to wrap the day name on a new line.)
  • Then, go to the Alignment tab:
    • Check Wrap Text
    • Set Horizontal Alignment to Center

  • Increase row height to fit the text.

It should look like this:

Step 2: Set Up the Employee Table

1. In column A, list your employees:
Example:

  • A6: Alice
  • A9: Ben
  • A12: Chloe

Each employee needs 3 rows:

  • Row 1: Work status
  • Row 2: Start time
  • Row 3: Finish time

2. In column B, input each employee’s standard work hours:

  • B6: 8 (Alice)
  • B9: 7 (Ben)
  • B12: 6 (Chloe)

It should look something like this:

Step 3: Add Drop-Downs for Work Status

1. Select the first row for each employee’s schedule (e.g., C6:AG6 for Alice).

2. Go to Data > Data Validation > List and enter:

Working,Day Off,Sick,Holiday

(Add/remove options from the list to suit your requirements.)

3. Copy the data validation to each employee’s status row.

4. Set the work status for each employee for the month.

Mine looks like this now:

Step 4: Colour-Code Work Statuses

1. Select all status cells (e.g., C6:AG28 to allow space for more employees).

2. Go to Home > Conditional Formatting > Highlight Cells Rules > Text that Contains.

3. Add rules like:

  • “Working” → blue fill
  • “Day Off” → grey fill
  • “Sick” → orange fill
  • “Holiday” → green fill

Step 5: Automatically Calculate Finish Times

1. In the second row for each employee, enter their start time (e.g., C7: 9:00 AM).

2. In the third row (e.g., C8), enter the formula:

=IF(AND(C6="Working",C7<>""), C7+TIME($B6+1,0,0), "")

This checks if the employee is working and has a start time, then adds standard hours +1 hour for lunch. Modify the +1 to suit your break duration.

3. Copy this formula across the row and down for other employees.

Step 6: Freeze Panes for Easy Scrolling

Select cell C6 > go to View > Freeze Panes > Freeze Panes

Now, names, standard hours and dates in row 5 stay visible while scrolling.ces (like Allocation), you can even skip the extra brackets after the @ sign:

Step 7: Add Visual Dividers Between Employees

1. Select all rows in the schedule (e.g., A6:AG28)

2. Go to Home > Conditional Formatting > New Rule > Use a formula
Use this formula:

=$B6="Finish"

3. Format with a green bottom border to separate each employee’s block.

4. Go to the View tab and turn off gridlines.

Step 8: Create a Dynamic Heading

1. In cell A1, enter:

="Work Schedule - " & TEXT(B3,"mmmm")

2. Format this row with green fill and white bold text for visibility.

3. While we’re formatting, let’s also add green fill to row 5 and format the font bold.

Step 9: Add Summary Figures (Optional but Useful)

1. Use COUNTIF to calculate how many days were worked:

  • In E3: label = Days Worked
  • In F3:
=COUNTIF(C6:AG30,"Working")

Repeat for “Sick” and “Holiday” if you want more summaries.

2. Add icons using Insert > Icons, search for:

  • Computer (working)
  • Doctor (sick)
  • Sun (holiday)

Resize and colour to match your theme.

Step 10: Customize and Expand

You can change the standard hours, start times, or status drop-downs to suit your team.

To add new employees, just insert a new 3-row block and copy formatting and formulas.

    • Hi Lillien,

      This works in Excel for Microsoft 365 or Excel 2021 onwards. If you have an earlier version of Excel, you can generate the dates manually or using a slightly different formula. If you get stuck, please post your question on our Excel forum where you can also upload a sample file and we can help you further.
