How it's calculated: count the days from today to December 31, 2043 (6370 days), divide by 7, and round down — 6370 ÷ 7 = 910 full weeks. Subtracting the current week number from the year's total also gets close, but drifts in 53-week ISO years (2043 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)
