How many days are between Presidents' Day and Memorial Day?

Q: How many days are between Presidents' Day and Memorial Day?

105 days. Presidents' Day falls on Monday, February 15, 2027 and Memorial Day on Monday, May 31, 2027, which is 105 days later — 15 weeks, or 75 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.
