小時計算器幫助您計算兩個日期和時間之間的精確時間差，並支援排除休息時間。這個工具特別適用於計算工作時間、專案時間跟蹤，以及任何需要精確計算時間的場景。
It shows elapsed time between the start and end datetimes, net work time after one break deduction, and both hours/minutes and decimal-hour formats.
Enter the next calendar date explicitly, such as 2026-07-24 22:00 to 2026-07-25 06:00. The page does not automatically treat an earlier end time as the next day.
No. It calculates elapsed and net hours only; it has no hourly rate, weekly total, overtime multiplier, holiday, or local labor-law rules.
