About January 2027
January 2027 has 31 days. It begins on a Friday and ends on a Sunday, which gives the month five Fridays, Saturdays and Sundays — and only four of every other weekday. Of its 21 weekdays, 2 are federal holidays, leaving 19 working days.
Because 1 January falls on a Friday, the first days of the month still belong to ISO week 53 of 2026; ISO week 1 of 2027 does not begin until the first Monday.
New Year's Day falls on Friday, January 1, 2027. Birthday of Martin Luther King, Jr. falls on Monday, January 18, 2027.
The month runs from Friday, January 1, 2027 to Sunday, January 31, 2027, spanning ISO weeks 53 to 4.
