Memorial Day falls on Monday, May 25, 2026 and Halloween on Saturday, October 31, 2026, which is 159 days later — 22 weeks and 5 days, or 114 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.
