Q: How many days are between St. Patrick's Day and Labor Day?

173 days. St. Patrick's Day falls on Wednesday, March 17, 2027 and Labor Day on Monday, September 6, 2027, which is 173 days later — 24 weeks and 5 days, or 123 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.
