Open tool →About these time & date
Every tool below is free, works in your browser, and needs no account.
- Does the duration calculator handle overnight shifts?
- Yes — end times earlier than start times are treated as next-day, so night shifts total correctly.
- How far back does the day-of-week finder go?
- It uses the proleptic Gregorian calendar, so it works for historical and future dates alike.
- Does the time card handle overtime?
- Yes — hours over 40 per week are paid at 1.5× for the gross-pay total.
