Free Time & Date Calculators
Fahahu provides free online time and date tools for converting time zones, checking live world times, comparing locations, planning international meetings and performing calendar calculations.
Time and date calculations can become complicated because time zones use different UTC offsets, daylight saving rules change during the year, and calendar months contain different numbers of days.
Time Zone Tools
Use the Time Zone Converter when you need to convert a specific date and time between two locations. The World Clock is useful for monitoring several locations at once, while the Time Difference Calculator shows how far ahead or behind one location is compared with another.
For calls involving several countries, the Meeting Time Planner compares working hours and displays them on a shared timeline to make international scheduling easier.
Date Difference Calculator
The Date Difference Calculator measures the duration between two calendar dates. It can show the exact difference in years, months and days together with total days, complete weeks, weekdays and weekend days.
Date Calculator
The Date Calculator works in the opposite direction. Start with a known date and add or subtract years, months, weeks or days to calculate a new future or past date.
Calendar Days and Business Days
Calendar days include every day of the week. Business-day calculations can be useful when estimating work schedules because Saturdays and Sundays can be skipped. Public holidays vary by location and are not automatically excluded by Fahahu’s current date calculators.
Daylight Saving Time and UTC Offsets
The time difference between two places may change during the year because some regions observe daylight saving time while others do not. Fahahu’s time-zone tools use time-zone information available in modern browsers so applicable UTC offsets and daylight-saving rules can be reflected.
