How many days are in August?

Q: How many days are in August?

31 days. August 2026 runs from Saturday, August 1, 2026 to Monday, August 31, 2026: 31 days in all, 21 of them weekdays and 10 weekend days. No federal holiday falls inside it, so every weekday is a working day. Both end days are counted, which is how a calendar counts a month rather than how a date difference counts one. Business days here are Monday to Friday; federal holidays are listed separately because private employers do not all take the same ones.

Business days are Monday–Friday with no holiday exclusions.
Adding months keeps the day of month, clamped to the target month's length.
