How many days are between Memorial Day and Father's Day?

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

20 days. Memorial Day falls on Monday, May 31, 2027 and Father's Day on Sunday, June 20, 2027, which is 20 days later — 2 weeks and 6 days, or 14 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.
