How to Create a Yearly Excel Calendar
Creating a calendar in Excel is simple with the SEQUENCE function. Follow these steps to make an interactive yearly calendar.
Step 1: User Input
- Type the year in cell D2.
Step 2: Create Weekday Headers
- Enter weekday names (Sun to Sat) in cells B4 to H4.
Step 3: Use the SEQUENCE Function
Understanding SEQUENCE:
The SEQUENCE function generates a sequence of numbers in a specified number of rows and columns. Here’s the syntax:
SEQUENCE(rows, [columns], [start], [step])- rows: Number of rows to return.
- columns: (Optional) Number of columns to return. Default is 1.
- start: (Optional) Starting number in the sequence. Default is 1.
- step: (Optional) Step value for incrementing numbers. Default is 1.
Using the DATE Function:
The DATE function returns the date that corresponds to the specified year, month, and day. Here’s the syntax:
DATE(year, month, day)- year: A number that represents the year.
- month: A number that represents the month.
- day: A number that represents the day.
To create a calendar, we need a 7-day by 54-week table.
In cell B5, type the formula:
=SEQUENCE(54, 7, DATE(D2, 1, 1), 1)This formula will generate dates starting from January 1 of the year entered in D2.
Step 4: Format Dates
- Select Date Cells: Highlight all cells that contain dates.
- Format as Dates: Go to Home -> Number Format -> Short Date or Long Date. This will make sure the cells display as dates instead of numbers.
This step ensures that the generated numbers are displayed as recognizable dates.

Step 5: Adjust for the First Sunday
To start the calendar on the first Sunday of the year, use this formula:
=SEQUENCE(54, 7, DATE(D2, 1, 1) - WEEKDAY(DATE(D2, 1, 1)) + 1, 1)Breaking Down the Formula:
- DATE(D2, 1, 1): This part generates the date for January 1 of the year entered in D2.
- WEEKDAY(DATE(D2, 1, 1)): This part determines the day of the week for January 1. WEEKDAY returns a number from 1 (Sunday) to 7 (Saturday).
- DATE(D2, 1, 1) – WEEKDAY(DATE(D2, 1, 1)) + 1: This calculation adjusts the date to the first Sunday of the year. By subtracting the weekday number from January 1 and adding 1, you ensure the start date is a Sunday.
This formula adjusts the start date to the first Sunday of the given year, even if January 1 is not a Sunday.
Step 6: Add Borders
- Select Calendar Range: Highlight the entire range of the calendar.
- Add Borders: Go to Home -> Borders -> All Borders. This will create a grid around each date, making the calendar easier to read.
Adding borders gives the calendar a clean, organized appearance.
Step 7: Highlight Out-of-Year Dates
Use Conditional Formatting to fade dates not in the selected year:
- Select Date Cells: Highlight the cells containing dates.
- Apply Conditional Formatting:
- Go to Home -> Conditional Formatting -> New Rule.
- Select “Use a formula to determine which cells to format.”
- Enter the formula:
=$D$2 <> YEAR(B5)- Choose a light-gray font color and apply.
This step helps differentiate dates from the previous or next year, making the calendar more user-friendly.
Step 8: Shade Every Other Month
To shade alternating months, use Conditional Formatting:
- Select Date Cells: Highlight the date cells.
- Apply Conditional Formatting:
- Go to Home -> Conditional Formatting -> New Rule.
- Select “Use a formula to determine which cells to format.”
- Enter the formula:
=MOD(MONTH(B5), 2)- Choose a pale-green fill color and apply.
Why Use the Excel MOD Function?
We use MOD to identify odd and even months. By dividing the month number by 2, MOD returns either 0 (even months) or 1 (odd months). This helps in applying different formats based on the month.

Shading every other month makes it easier to distinguish between different months at a glance.
How to Fix Calendar Shading Issues
If your Excel calendar doesn’t have a 54-week year, the shading at the bottom might look odd. Here’s a simple way to fix it using Conditional Formatting.
Why Does a 54-Week Year Occur?
A 54-week year can happen because of the way weeks are counted in a calendar. Normally, a year has 52 weeks, but sometimes an extra week gets added. This is because a year actually has about 52 weeks and 1 day (or 2 days in a leap year). Over time, these extra days can accumulate and result in an additional week in the calendar.
This is easily fixed by reordering the Conditional Formatting rules.
- Click any cell in the calendar table.
- Go to the Home tab, then click Conditional Formatting and select Manage Rules.
- In the Manage Rules dialog box:
- Move the “out-of-year” rule to the top.
- Move the shading rule to the second position.
- Check the “Stop if True” box for the first rule.
By reordering the rules, your calendar will display correctly without unnecessary shading. This quick fix ensures your calendar looks clean and professional.
How to Make a Monthly Excel Calendar
You can create a monthly calendar template in Excel with a single formula. Follow these steps to generate a calendar for any month and year.
Step 1: Enter Month and Year:
- Type the month number in cell A2.
- Type the year in cell B2.
Step 2: Enter the LET Formula
Copy and paste the following formula into the cell where you want your calendar to start:
=LET(m, A2, y, B2, d, 1, dw, {"Sun","Mon","Tue","Wed","Thu","Fri","Sat"}, sq, SEQUENCE(8), dt, DATE(y, m, d), fd, DATE(y, m, 1), wd, WEEKDAY(fd), dts, SEQUENCE(8, 7, fd-wd-13), arr, IF(MONTH(dts)=m, TEXT(dts, "d"), ""), r1w, TEXT(dt, "mmm yyy"), r2w, REPT(dw, SEQUENCE(2, , 1, 0) ), IFS(SEQUENCE(8, 7)=3, r1w, sq=2, r2w, TRUE, arr) )Explanation:
- LET Function: Assigns names to parts of the formula for simplicity.
- SEQUENCE Function: Generates a sequence of numbers for the calendar.
- DATE Function: Creates date values based on the month and year.
- WEEKDAY Function: Finds the day of the week for the first day of the month.
- TEXT Function: Formats the dates to show only the day number.
This formula will create a calendar that starts on Sunday.
Step 3: Adjust for Monday Start (Optional)
If you prefer the calendar to start on Monday, use this modified formula:
=LET(m, A2, y, B2, d, 1, dw, {"Mon","Tue","Wed","Thu","Fri","Sat","Sun"}, sq, SEQUENCE(8), dt, DATE(y, m, d), fd, DATE(y, m, 1), wd, WEEKDAY(fd, 2), dts, SEQUENCE(8, 7, fd-wd-13), arr, IF(MONTH(dts)=m, TEXT(dts, "d"), ""), r1w, TEXT(dt, "mmm yyy"), r2w, REPT(dw, SEQUENCE(2, , 1, 0) ), IFS(SEQUENCE(8, 7)=3, r1w, sq=2, r2w, TRUE, arr) )By using these formulas, you can easily create a monthly calendar template in Excel.
