How many days are between Labor Day and Columbus Day?

Q: How many days are between Labor Day and Columbus Day?

35 days. Labor Day falls on Monday, September 6, 2027 and Columbus Day on Monday, October 11, 2027, which is 35 days later — 5 weeks, or 25 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.
