Hours Calculator
Pleasure and action make the hours seem short — when counting time, it's better not to trust your intuition — use the hours calculator instead.
This all-in-one hours calculator includes five powerful tools:
- An add hours calculator (payroll / timesheet tool)
- An hour converter (hours to days, minutes to hours, and more)
- A time between two times calculator (hours between start and end time)
- A time card calculator (weekly work hours with pay and overtime)
- An hours from now calculator (what time will it be in X hours)
Add Hours Calculator
Choose the Add Hours mode to sum multiple time entries. Enter hours, minutes, and seconds for each row. You can add up to 10 rows and use negative values to subtract time. This is the perfect payroll hours calculator — for example, if you worked 3 h on Monday, 6 h 45 min on Tuesday, and 7 h 55 min on Friday, just enter those values and get the weekly total instantly.
Hour Converter
Select Hour Converter to convert any time value between seconds, minutes, hours, days, and weeks. Enter your value, pick the source unit and target unit. For example: 235 hours = 9 days 19 hours. The converter shows you all equivalent values in a single table — handy as a minutes-to-hours calculator, an hours-to-days calculator, or any other time unit converter you need.
Hours Between Two Times
Use the Between Two Times mode to calculate how many hours and minutes elapsed between a start and an end time. Both 12-hour (AM/PM) and 24-hour formats are supported. If the end time is earlier than the start time, the calculator automatically assumes the period crosses midnight and adjusts the result accordingly. Result is shown in hours + minutes and as a decimal.
Example: You worked from 9:45 AM to 4:25 PM. Enter start = 9 h 45 min AM and end = 4 h 25 min PM. Result: 6 h 40 min.
Time Card — Weekly Hours Calculator
The Time Card mode is your weekly work hours calculator. Enter start time, end time, and unpaid break (in minutes) for each working day — Monday through Friday, with optional Saturday and Sunday. The calculator shows net hours per day and the weekly total.
Under Hourly Pay Rate you can enter your wage to compute your total weekly earnings. Supported currencies include USD ($), RUB (₽), EUR (€), GBP (£), JPY (¥), CAD, AUD, CHF, CNY, INR, BRL, and MXN. Tick Include Overtime Pay to set your regular hours threshold (default: 40 h/week) and overtime multiplier (default: ×1.5) to see overtime and regular pay broken out separately.
Hours From Now Calculator
The Hours From Now mode adds a given number of hours and minutes to the current server time and shows you the resulting time. Useful for scheduling, shift planning, or answering "what time will it be in 5 hours and 30 minutes?"
American vs. Metric (24-Hour) Time Format
For the Between Two Times and Time Card modes you can switch between the American 12-hour (AM/PM) format and the metric 24-hour format. Results are always displayed in both formats for convenience.
