Why a 13-Week Lookback Matters
A 13-week window covers 91 days, 65 business days, and approximately 3 calendar months.
How 13 Weeks Compares to Other Timeframes
A 13-week window covers exactly 91 calendar days, 65 business days, and 26 weekend days. Because a week is always exactly 7 days, this calculation is perfectly precise — unlike month-based calculations which vary 28-31 days. The day of the week always repeats when adding or subtracting whole weeks, so the target date will fall on the same weekday as today. This makes weeks the most predictable date unit for recurring schedules, weekly meetings, and appointment planning.
