- Product
- Excel
- Device & OS
- not provided
- Scenario
- Calculating specific recurring weekdays near the end of a month for scheduling, payroll processing, or monthly reporting purposes.
- Observed behavior
- The goal is to input a reference date or specific year and month, and have Excel automatically output the correct date for that month's final Wednesday.
Ensure that your reference date cells are properly formatted as dates in Excel, and that you have a clear target cell selected to receive the calculated result.
Use EOMONTH and WEEKDAY Functions
This is the most straightforward method to find the last Wednesday of a month based on an existing date in your worksheet.
The EOMONTH function determines the last day of the target month. By combining it with the WEEKDAY function, you can dynamically calculate the exact number of days to step back to find the correct Wednesday.
Enter any valid date within your target month into cell A1. For example, enter '9/15/2026'.
Select the empty cell where you want the result to appear, and enter the formula: =EOMONTH(A1,0)-WEEKDAY(EOMONTH(A1,0)-3,1)
Press Enter to apply the formula. If the result appears as a 5-digit number (like 46300), right-click the cell, select 'Format Cells', choose 'Date' under the Number tab, and click OK.
Use the LET Function for Dynamic Year and Month Variables
Ideal for scenarios where you supply the specific year and month as separate standalone numbers rather than a full date.

How can I modify this formula to find the last Thursday of a month instead?
