How many days are between Thanksgiving and St. Patrick's Day?

Q: How many days are between Thanksgiving and St. Patrick's Day?

111 days. Thanksgiving falls on Thursday, November 26, 2026 and St. Patrick's Day on Wednesday, March 17, 2027, which is 111 days later — 15 weeks and 6 days, or 79 business days counting Monday to Friday only. The first day is not counted and the last one is, the same way a calendar counts a stay. One of these two moves around the calendar, so the gap is not the same every year — the table below gives the next five.
