Starting today, Wednesday, July 22, 2026: 0 weeks, or 0 days (0 fortnights), left in 2015. 2015 has 53 ISO weeks. This page recalculates on every visit — bookmark or share the link below.
How it's calculated: count the days from today to December 31, 2015 (0 days), divide by 7, and round down — 0 ÷ 7 = 0 full weeks. Subtracting the current week number from the year's total also gets close, but drifts in 53-week ISO years (2015 is one: it has 53 ISO weeks), so we count days instead.
In Excel or Google Sheets:=INT((DATE(YEAR(TODAY()), 12, 31) - TODAY()) / 7)or, rounding to the nearest week instead of down:=ROUND((DATE(YEAR(TODAY()), 12, 31) - TODAY()) / 7, 0)
