-
统计工作时长 · Measuring Working Hours:
例如 09:00–12:00 + 13:30–18:00,可以分别计算每一段,再相加得到当天总工作时长。
For example, 09:00–12:00 and 13:30–18:00 can be calculated separately and then added together to get the total working hours of the day. -
加班与项目时间记录 · Overtime & Project Time Tracking:
用于记录某个任务、项目或加班的开始与结束时间,便于后续进行成本核算或绩效统计。
Record the start and end time of tasks, projects, or overtime for later cost analysis or performance evaluation. -
跨午夜班次 · Cross-Midnight Shifts:
夜班或通宵场景下,如果结束时间早于开始时间,本工具自动视为跨越午夜, 按次日结束进行计算(不需手动换算)。
For night shifts or overnight work, if the end time is earlier than the start time, the tool automatically treats it as crossing midnight and assumes the end time is on the next day. -
与“日期差计算器”的区别 · Difference from Date Difference Tool:
本工具适用于 24 小时以内的时间差统计; 如果需要按天、周或更长周期计算,请使用“日期差计算器”。
This calculator is designed for elapsed time within 24 hours. For longer periods (days, weeks, etc.), please use the Date Difference Calculator.
说明:本工具按 24 小时制并假设时间在同一时区内,不考虑夏令时切换、时区变化等复杂情形。
Note: This tool uses a 24-hour clock within a single time zone, and does not handle daylight saving
time changes or time zone differences.
