What Is Time Duration?
Time duration is the amount of time that passes between two points, or the length of a time interval. This calculator finds duration between clock times, adds or subtracts duration from a time, converts between 7 time units (seconds to years), and computes end time from a start time and elapsed duration — with automatic midnight-crossing support.
4 Calculation Types
समय के बीच की अवधि
Enter start and end time. Duration can cross midnight. Shows result in seconds, minutes, hours, and days.
Add / Subtract
Add or subtract hours, minutes, seconds, or days from any clock time.
इकाइयों को परिवर्तित करें
Convert between seconds, minutes, hours, days, weeks, months, and years.
Elapsed Time
From a start time and elapsed duration, find when it ends. Shows days elapsed.
Key Formulas
अवधि: End − Start (या 86400 − Start + End)
जोड़ना: Time + Duration → mod 86400
Convert: Value × FromFactor ÷ ToFactor
Elapsed: Start + Duration = End
महत्वपूर्ण नोट्स
- 24 घंटे के प्रारूप का उपयोग करें: 0:00 से 23:59 तक। मध्यरात्रि क्रॉसिंग को स्वचालित रूप से नियंत्रित किया जाता है।
- Months and years are approximate: 1 month = 30 days, 1 year = 365 days.
- बीता हुआ समय बताता है कि अंत समय कितने दिन बाद आता है।
