Panduan Pengguna Lengkap

What Is Time Duration?

Tempoh masa ialah jumlah masa yang berlalu antara dua titik, atau panjang selang masa. Kalkulator ini mencari tempoh antara masa jam, menambah atau menolak tempoh masa, menukar antara 7 unit masa (saat kepada tahun) dan mengira masa tamat dari masa mula dan tempoh berlalu — dengan sokongan lintasan tengah malam automatik.

4 Calculation Types

Tempoh Antara Masa

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.

Tukar Unit

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

Tempoh: End − Start (atau 86400 − Start + End)

Tambah: Time + Duration → mod 86400

Convert: Value × FromFactor ÷ ToFactor

Elapsed: Start + Duration = End

Nota Penting

  • Gunakan format 24 jam: 0:00 hingga 23:59. Lintasan tengah malam dikendalikan secara automatik.
  • Months and years are approximate: 1 month = 30 days, 1 year = 365 days.
  • Masa berlalu menunjukkan berapa hari kemudian masa akhir jatuh.
