How to use this quarter count
The baseline formula is calendar days - weekend days = weekday business days. For Q1 2029, that is 90 calendar days - 25 weekend days = 65 weekday business days, before public holidays, office closures, or custom non-working days.
Capacity planning
Start with 65 weekday slots, subtract PTO, public holidays, company shutdowns, and meeting-heavy days, then multiply by available contributors to estimate realistic delivery capacity.
Payroll and billing
Use the quarter dates (Monday, January 1, 2029 to Saturday, March 31, 2029) to align invoices, subscription renewals, contractor schedules, and biweekly or monthly payroll cutoffs.
Editorial calendar
Q1 2029 starts on a Monday, giving January the highest weekday count in the quarter and making it useful for front-loaded launches or planning sprints.
