This countdown stays on 2027. For a countdown that follows the current year, use weeks left in the year.
=MAX(0, INT((DATE(2027, 12, 31) - TODAY()) / 7))or, rounding to the nearest week instead of down:=MAX(0, ROUND((DATE(2027, 12, 31) - TODAY()) / 7, 0))Both formulas return zero after the year ends.There are 63 full weeks (443 days) left in 2027, counting from today to December 31, 2027.
There are 443 days left in 2027.
Count the days from today to December 31, 2027, then divide by 7 and round down: 443 days ÷ 7 = 63 full weeks. Subtracting week numbers also works but can drift in 53-week ISO years.
=MAX(0, INT((DATE(2027, 12, 31) - TODAY()) / 7)) — or use =MAX(0, ROUND((DATE(2027, 12, 31) - TODAY()) / 7, 0)) to round to the nearest week. Both return zero after the year ends. Works in Excel and Google Sheets.
There are 31 fortnights (two-week periods) left in 2027.
