Why a 20-Week Lookback Matters
A 20-week window covers 140 days, 100 business days, and approximately 4.6 calendar months.
How 20 Weeks Compares to Other Timeframes
A 20-week window covers exactly 140 calendar days, 100 business days, and 40 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.
