FAQ
How is the "week of month" counted?
The week containing the 1st of the month is week 1: days 1-7 are week 1, days 8-14 are week 2, and so on in blocks of 7 (the day-of-month divided by 7, rounded up).
How does this relate to something like "the 3rd Monday"?
This tool's "week of month" always matches how many times that weekday has occurred in the month so far โ e.g. it directly tells you it's the "3rd Monday". Handy for checking recurring rules like "team meeting on the 2nd Tuesday of every month".
Is this different from ISO week numbers?
Yes. This tool calculates the week within the month, counting from the 1st. For week numbers spanning the whole year (ISO 8601 style), use the Week Number Calculator instead.
