Q: How many days are between Martin Luther King Jr. Day and Valentine's Day?

27 days. Martin Luther King Jr. Day falls on Monday, January 18, 2027 and Valentine's Day on Sunday, February 14, 2027, which is 27 days later — 3 weeks and 6 days, or 19 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. Both dates are fixed, so the gap is the same every year apart from leap-year shifts in the weekdays.
