Q1 2026 runs from Thursday, January 1, 2026 to Tuesday, March 31, 2026: 90 days in all, 64 of them weekdays and 26 weekend days. 3 federal holidays fall inside it — New Year's Day (January 1, 2026), Martin Luther King Jr. Day (January 19, 2026), Presidents' Day (February 16, 2026) — so 61 working days are left once those are taken off. 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.
