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

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

126 days. Valentine's Day falls on Sunday, February 14, 2027 and Father's Day on Sunday, June 20, 2027, which is 126 days later — 18 weeks, or 90 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.
