The ability to calculate work hours and overtime comes up more often than most people expect — in professional work, academic projects, and everyday planning. Be careful with "months" as a unit — adding one month to January 31 does not have a clear answer. Timezone handling is notoriously tricky — daylight saving transitions can shift dates by a day in edge cases. A Unix timestamp converts to a human-readable date by dividing into days since the epoch and applying timezone offset. Run the calculation with your best-case and worst- case assumptions to bracket the likely outcome.
