Notes
Calendar years
Years are subtracted as calendar years (12 months). “1 year ago” is not always the same as “365 days ago”.
Fractional years
A fractional year is treated as a fractional number of months and uses the length of the adjacent month in your local time zone.
Common years-ago questions
Use this to keep everyone referencing the same timestamp in chat, tickets, or calendars.
Years ago answers questions like: What time was it 2 years ago?
Enter whole or decimal years. Whole years follow the calendar. A fractional year is based on the length of the adjacent month in your local time zone. Choose “Current date and time” to use a live base time that updates every second, or choose “Custom date and time” to work from a fixed reference.
The output includes the target date, 24-hour time, 12-hour time, and time zone, plus ISO 8601 and Unix timestamps (seconds and milliseconds). This is commonly used for time tracking, incident timelines, and “how long ago” reporting. Across daylight saving time changes, the clock time can shift by an hour even when the elapsed time matches the offset.
Notes
- If the offset is 0, the target time is the same as the base time.
- Calendar years do not have a fixed length. Adding 1 year is not the same as adding 30 days.
- If the offset is 0, the target time is the same as the base time.
- The calculator uses your browser’s local time zone for the base and the displayed local time.

Using a custom baseline
Use this for incident timelines, logs, and “when did this happen?” questions.
