How the calculation works

Monthly time = time per workday × workdays in the month. The day count is entered by you; fractional full-day equivalents are allowed. Holidays and attendance are not fetched. 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
