February
February begins on the same day of the week as March and November in common years and on the same day of the week as August in leap years. February ends on the same day of the week as January in common years and October every year, as each other's last days are exactly 4 weeks (28 days) and 35 weeks (245 days) apart respectively. In a leap year, February is the only month to begin and end on the same day of the week.
