How the calculation works

Annual time = time per week × working weeks in the year. The week count is entered by you; fractional full-week equivalents are allowed. No standard working year is assumed. Durations can be minutes alone or labelled d, h, min and sec; a duration day means 24 hours. This arithmetic does not determine payroll, overtime, break entitlement, rounding policy or legal compliance. A plain duration is minutes; labelled h, min, sec and d are also accepted. One duration day is 24 hours. Results round to the nearest second, and a positive duration below half a second is labelled Less than 1 sec. Entered decimal arithmetic is applied before display rounding. Numeric inputs/results and durations in seconds are bounded by magnitude 9,007,199,254,740,991.

Practical tip

Enter recorded time on the same paid, worked or billed basis. Include breaks only when appropriate for that basis.
