Date & Time Converters
Convert between time units, time zones and clock formats.
Time does not follow the base-10 rules of most other units, and that is the source of most conversion mistakes. Payroll and timesheets need decimal hours, where 6 hours 25 minutes is about 6.42 rather than 6.25. The time to decimal converter handles that in both directions, including minutes to hours. Convert first, then round once at the end, because rounding each step is how small payroll errors add up.
Clock formats have their own converters: the 24-hour to 12-hour converter translates between AM/PM and the 24-hour (military) clock, and the time zone converter shows a date and time in another zone. The time converter changes an amount of time from one unit to another, and the Unix time converter translates between timestamps and readable dates.

All date & time converters
- Time Zone ConverterEnter a date and time, choose the zone it is in and the zone you want, and read the converted time in your own locale format and on a 24 hour clock.
- 24 Hour to 12 Hour Time ConverterChoose a direction, type a time such as 17:30 or 5:30 PM, and the converted time appears underneath. A chart of all 24 hours is included for a quick lookup.
- Time ConverterEnter an amount of time, pick the unit it is in and the unit you want, and the answer appears straight away. Thirteen units are supported, from nanoseconds to centuries.
- Time to Decimal ConverterEnter hours and minutes and the converter returns the total as decimal hours or as minutes. Empty boxes count as zero, and the answer is rounded to two decimal places.
- Unix Timestamp ConverterSwitch between epoch seconds and calendar dates in either direction. Paste a timestamp to see the date in UTC and in your own time zone, or enter a date and time to get the matching timestamp.
