Find the date of the third Tuesday of a month

The job

“Patch Tuesday”, “the third Saturday shift”, “last Friday of the month pay run” — schedules written as an nth weekday need a concrete date before you can book a room or set a reminder.

How to do it

Choose “find”, enter the year and month, pick the weekday and which occurrence — 1st through 4th or “last”. The result gives the date plus every matching weekday that month, so you can copy the whole series.

• “Last” always resolves even when a month has only four of that weekday.
• “Check a date” does the reverse: paste a date to see it is the nth weekday of its month.

Worked example

The team's review is the second Tuesday of October 2026. Entering 2026, month 10, Tuesday, 2nd returns 2026-10-13 — and lists the month's other Tuesdays (6th, 20th, 27th) for planning around holidays.

Limits

Gregorian calendar only, years 1–9999, using the browser's local calendar. Fifth occurrences are reachable only via “last” — a month with five Tuesdays still reports the fourth as the second-to-last. Weekday names follow the locale but the calendar math is locale-independent.
