Valentine's Day falls on Sunday, February 14, 2027 and St. Patrick's Day on Wednesday, March 17, 2027, which is 31 days later — 4 weeks and 3 days, or 23 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.
