St. Patrick's Day falls on Wednesday, March 17, 2027 and Memorial Day on Monday, May 31, 2027, which is 75 days later — 10 weeks and 5 days, or 53 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. One of these two moves around the calendar, so the gap is not the same every year — the table below gives the next five.
