How many days are between New Year's Eve and St. Patrick's Day?

Q: How many days are between New Year's Eve and St. Patrick's Day?

76 days. New Year's Eve falls on Thursday, December 31, 2026 and St. Patrick's Day on Wednesday, March 17, 2027, which is 76 days later — 10 weeks and 6 days, or 54 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. Both dates are fixed, so the gap is the same every year apart from leap-year shifts in the weekdays.
