Countdown Calculator

Count down to an event across days, hours and minutes.

About Countdown Calculator

Converting to total minutes gives a single figure for comparison, while the working-day count is what matters for delivery planning. A 45-day countdown contains only about 32 working days. Countdowns quoted in calendar time consistently make deadlines feel further away than the available working time justifies.

Formula

Countdown

Total minutes = days × 1,440 + hours × 60 + minutes

working days remaining
Scaled from calendar days by the working-week ratio

  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
