About This Calculator

This time calculator handles four common time operations: finding the difference between two clock times, adding or subtracting a duration from a time, converting between time units (seconds, minutes, hours, days, weeks), and calculating the duration between a start and end time — with automatic midnight-crossing support.

Key Formulas

Difference: |Time₂ − Time₁| (in seconds)

Aggiungere: Time + Amount → mod 86400

Convert: Value × FromFactor ÷ ToFactor

Durata: End − Start (O 86400 − Start + End)

Note importanti

  • Utilizza il formato 24 ore: dalle 0:00 alle 23:59. Ad esempio, 14:30 = 14:30.
  • Duration handles midnight crossing: Start 22:00, End 06:00 = 8 hours.
  • Aggiungi/sottrai gli avvolgimenti intorno alle 24 ore. Sottraendo la mezzanotte passata si aggiungono 24 ore.
  • 1 giorno = 86.400 secondi, 1 settimana = 604.800 secondi.
