How many days are between Christmas and Mother's Day?

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

135 days. Christmas falls on Friday, December 25, 2026 and Mother's Day on Sunday, May 9, 2027, which is 135 days later — 19 weeks and 2 days, or 95 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.
