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)
Ajouter: Time + Amount → mod 86400
Convert: Value × FromFactor ÷ ToFactor
Durée: End − Start (ou 86400 − Start + End)
Remarques importantes
- Utilisez le format 24 heures : 0h00 à 23h59. Par exemple, 14h30 = 14h30.
- Duration handles midnight crossing: Start 22:00, End 06:00 = 8 hours.
- Ajouter/soustraire des tours environ 24 heures. La soustraction après minuit ajoute 24h.
- 1 jour = 86 400 secondes, 1 semaine = 604 800 secondes.
