Mother's Day falls on Sunday, May 9, 2027 and Father's Day on Sunday, June 20, 2027, which is 42 days later — 6 weeks, or 30 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.
