Notes

Decimal days

Decimal days are treated as elapsed time (24 hours per day). For example, 0.5 days is 12 hours.

Daylight saving time

A one-day offset is 24 hours of elapsed time. Around a daylight saving time change, the clock time may shift by an hour.

Common days-ago questions

Use this to keep everyone referencing the same timestamp in chat, tickets, or calendars.

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.

Days ago answers questions like: What time was it 30.5 days ago?

Enter whole or decimal days. Decimal values are treated as a fraction of a day (for example, 1.5 days is 1 day plus half of one). 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.

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).
  • Decimal days are treated as elapsed time (for example, 0.5 days is half of one day).
  • If the offset is 0, the target time is the same as the base time.
  • Decimal days are treated as elapsed time (for example, 0.5 days is half of one day).

Using decimal days

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

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).
  • The calculator uses your browser’s local time zone for the base and the displayed local time.
  • If the offset is 0, the target time is the same as the base time.

Using a custom baseline

Use this when you need a human-readable time plus a machine-readable timestamp.
