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

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

84 days. Valentine's Day falls on Sunday, February 14, 2027 and Mother's Day on Sunday, May 9, 2027, which is 84 days later — 12 weeks, or 60 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.
