What counts as a "week"? The calculator uses 7-day weeks measured from your reference date. 2026 has 365 days = 52 weeks + 1 day. A standard non-leap year has 52 full weeks plus one extra day, which is why your birthday lands on a different weekday each year (and skips two weekdays after a leap year).
