How many days are between Christmas Eve and Father's Day?

Q: How many days are between Christmas Eve and Father's Day?

178 days. Christmas Eve falls on Thursday, December 24, 2026 and Father's Day on Sunday, June 20, 2027, which is 178 days later — 25 weeks and 3 days, or 126 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.
