Week of the Month Calculator
Find which week of the month a date falls in.
Which week of the month?
Plenty of schedules run on the week within a month — the first Friday, the third Monday — and monthly reports often break down by week. This tool tells you which week of the month any date falls in.
It counts weeks from the first of the month, taking the starting weekday into account. A date on the 11th typically lands in the second or third week depending on how the month begins.

Frequently Asked Questions
How is the week counted?
Weeks are counted from the first of the month. The days 1 to 7 are week 1, 8 to 14 are week 2, and so on, adjusted for the starting weekday.
Why does this matter?
Recurring events like the second Tuesday of the month, and monthly reporting, rely on the week number within the month.
Is this the ISO week?
No. The ISO week number counts weeks in the year; this counts weeks within the month.
