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

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

125 days. Columbus Day falls on Monday, October 12, 2026 and Valentine's Day on Sunday, February 14, 2027, which is 125 days later — 17 weeks and 6 days, or 89 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.
