Excel function · Dates
JOUR(DAY)
Returns the day of the month of a date, from 1 to 31.
What it does
DAY returns the day of the month as a number. It doesn't tell you the day of the week; that is WEEKDAY.
Syntax
=JOUR(serial_number)Arguments in square brackets are optional, and … means you can add more of the same. In this Excel language, arguments are separated by ;
Arguments
- serial_number
- The date to read, usually a cell.
Example
Which day of the month is the date in A2?
| A | B | |
|---|---|---|
| 1 | Date | Day |
| 2 | 2026-02-28 | 28 |
The formula in B2:
=JOUR(A2)Result: 28
2026-02-28 is the 28th day of February, so the result is 28.
Common mistakes
- Confusing it with the day of the week. Monday or Sunday comes from
WEEKDAY. - Using it to count days between dates. Subtract the dates, or use
DAYS.
