Martin Luther King Jr. Day falls on Monday, January 18, 2027 and Memorial Day on Monday, May 31, 2027, which is 133 days later — 19 weeks, or 95 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.
