Why the weekday matters
In 2027 it lands at the weekend, which for a fixed-date holiday usually means the observed day off moves to the nearest weekday. For travel and shopping it also means the surrounding days are busier than usual. Because a common year is 365 days, which is 52 weeks plus one day, a fixed-date occasion moves forward one weekday each year and two across a leap year. That is why Pi Day cycles through the whole week over a seven-year span rather than repeating on a simple schedule.
