Panduan Pengguna Lengkap

Apakah itu Kalkulator Tarikh?

A date calculator performs date-related calculations: difference between two dates, add or subtract time periods (years, months, weeks, days), days since a past date or until a future date, and which day of the week a date falls on. It handles leap years, varying month lengths, and year boundaries.

Difference = End Date − Start Date  |  Hari perniagaan = hari bekerja sahaja (Isnin–Jumaat)

Gunakannya untuk perancangan projek, kira detik, umur atau tempoh, tarikh akhir dan penjadualan.

Date Format

Gunakan YYYY-MM-DD (mis. 2025-02-15). Tarikh dari tahun 1 hingga 9999 disokong.
