How it's calculated: count the days from today to December 31, 2039 (4865 days), divide by 7, and round down — 4865 ÷ 7 = 695 full weeks. Subtracting the current week number from the year's total also gets close, but drifts in 53-week ISO years, 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)
