Free epoch converter, date-to-days calculator & age tool
The easyTime toolbox bundles every everyday date and time calculator into one fast, offline-friendly page: a Unix epoch converter, a days between dates calculator, date to days and days to date converters, a date comparison tool, an age calculator with a next-birthday countdown, and an ISO week-number lookup.
Unix timestamp & epoch tool
Convert Unix timestamps in seconds or milliseconds to human-readable local time, UTC, and ISO 8601 — or convert any date and time back into an epoch timestamp. A live clock shows the current epoch ticking in real time.
Days between dates & date to days
Count the days between two dates with a full calendar breakdown (years, months, days), weeks, business days excluding weekends, and totals in hours and minutes. Add or subtract days, weeks, months, or years from any date, and compare two date-times down to the minute.
Age calculator & week number
Calculate exact age in years, months, and days with totals in months, weeks, days, and hours, plus a countdown to the next birthday. Look up the ISO week number, quarter, day of year, leap-year status, and days in any month.
Frequently asked questions
How do I convert a Unix timestamp to a date?
Open the Epoch tab, paste any Unix timestamp in seconds or milliseconds, and you get the human-readable local time, UTC time, and ISO 8601 string instantly. You can also convert any date and time back into a Unix epoch timestamp.
How do I calculate days between two dates?
Use the Days Between tool: pick a start and end date to get the total days, calendar breakdown in years, months and days, weeks, business days excluding weekends, and the total in hours and minutes.
How do I add or subtract days from a date?
The Date ± Days tool adds or subtracts any number of days, weeks, months, or years from a date and shows the resulting weekday and how far the result is from today.
How accurate is the age calculator?
It computes your exact age in years, months, and days, plus totals in months, weeks, days, and hours, and counts down to your next birthday — all calculated on your device.
Can I use these date tools without internet?
Yes. Every calculation — epoch conversion, date to days, age calculation, date comparison — runs entirely in your browser. Install the app for one-tap offline access.
