Notes
Calendar months
Months are subtracted as calendar months, so “1 month ago” is not always the same as “30 days ago”.
Fractional months
A fractional month is based on the length of the adjacent month in your local time zone.
Common months-ago questions
Use this to keep everyone referencing the same timestamp in chat, tickets, or calendars.
Enter whole or decimal months. Whole months follow the calendar. A fractional month 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.
Months ago answers questions like: What time was it 3 months ago?
Notes
- Use “Custom date and time” when your baseline is not right now (for example, a shift start, a log entry, or a scheduled departure).
- Calendar months do not have a fixed length. Adding 1 month 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.
