DayProof: Date Calculator

Count the days between two dates, add or subtract business days, and find the date you need. DayProof is a free date calculator for everyday questions and work deadlines — with no ads and no account. CALCULATE A DATE OR COUNT DAYS • Add or subtract calendar days, business days, weeks, months, or years. • Count calendar days or working days between two dates. • Work backward from a deadline to find your latest start date. • Choose whether to include the start and end dates. SEE WHICH DAYS COUNT Review your result on an interactive calendar. Tap a date to see whether it was counted or skipped, and why. Check excluded weekends, holidays, and the rules behind the result. USE YOUR WORKING CALENDAR Choose your working weekdays and selected holiday calendar. Built-in calendars cover US Federal, Canada Federal, England & Wales bank holidays, and Australia National holidays. Create custom rule profiles for company closures and additional regional holidays. Choose how results move when they land on a non-working day. PLAN CONNECTED DEADLINES Build a project timeline with linked milestones, such as Notice → Response → Delivery.
