Question details

The user needs a formula to accurately determine the current financial week number for a fiscal year that specifically begins on the first Monday of July, rather than a fixed date like July 1st.

How to Calculate the Current Financial Week Starting on the First Monday of July

Product: Spreadsheets
Device & OS: not provided
Scenario: Setting up tracking or reporting for a custom financial calendar year that calculates periods in seven-day intervals starting from the first Monday in July.
Observed behavior: Standard week number functions do not align with a rolling fiscal start date, requiring a custom formula that dynamically locates the first Monday of July and counts weeks from that point.

Before you start

Verify whether you need to calculate the financial week for the current real-time date or for a column of specific historical dates, as this changes which cell references you will use in the formula.

Solution 1Recommended

Use a Custom Date and Math Formula

Use a combination of INT, TODAY, DATE, MOD, and WEEKDAY functions to calculate the number of seven-day periods that have passed since the first Monday in July.

This formula first determines the exact date of the first Monday in July for the current year. It then subtracts that date from today's date and divides the result by 7 to find the number of elapsed weeks.

Select the target cell

Click on the cell where you want the financial week number to be displayed.

Enter the fiscal week formula

Type the following formula into the formula bar: =INT((TODAY()-(DATE(YEAR(TODAY()),7,1)+MOD(8-WEEKDAY(DATE(YEAR(TODAY()),7,1),2),7)))/7)+1

Adapt for specific date cells

If you are evaluating a specific date stored in another cell (e.g., A2) instead of the current day, replace all instances of 'TODAY()' in the formula with 'A2'.

Press Enter to calculate

Press Enter to run the calculation. You can then use the fill handle to drag the formula down if applying it to a whole column of dates.

Handling Previous Financial Years: This specific formula calculates based on the current calendar year. If your date falls between January 1st and the first Monday of July, it technically belongs to the previous financial year, and the formula will need an IF statement to subtract 1 from the YEAR function for those dates.

Frequently Asked Questions

How do I change the formula if my fiscal year starts in a different month?

You can change the month parameter within the DATE function. In the formula, '7,1' represents July 1st. If your fiscal year starts in April, change the instances of '7,1' to '4,1'.

Why is my formula returning a negative week number?

This happens when the date you are checking occurs earlier in the year than the first Monday of July. For example, a date in May is evaluated against the July date of the same year, resulting in a negative difference. You must adjust the logic to reference the previous year for dates before July.

Does this formula work in older versions of spreadsheet software?

Yes, functions like TODAY, INT, MOD, DATE, and WEEKDAY are core functions that have been supported across nearly all major spreadsheet applications, including WPS Office and Excel, for decades.
