Deadline Calculator
Calculate a deadline from a start date and lead time. Shows both calendar-day and business-day deadlines.
CALENDAR DEADLINE
Friday, April 10, 2026
BUSINESS-DAY DEADLINE
Thursday, April 16, 2026
Business-day deadline excludes weekends, so it may be later than the calendar deadline.
π‘ Deadline and Lead Time Calculator
Enter a start date and the number of lead-time days to calculate when the deadline falls. The calculator shows two results: the calendar-day deadline (counting all days) and the business-day deadline (skipping weekends).
This distinction is critical for project management and contract compliance. A 14-day lead time gives you a calendar deadline of exactly 2 weeks later, but a business-day deadline that's approximately 20 calendar days later (accounting for 4 weekends).
Start today + 14 lead days β Calendar deadline: 2 weeks later. Business deadline: ~20 calendar days later (skips weekends). Always clarify which type your stakeholder means.
