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

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

193 days. Labor Day falls on Monday, September 6, 2027 and St. Patrick's Day on Friday, March 17, 2028, which is 193 days later — 27 weeks and 4 days, or 139 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.
