# Dates and times

The API always uses UTC for dates and times.

> [!WARNING]
> Always send dates and times in **UTC**. That applies to every request, including values in `filters`. A time in any other time zone ends up off by the difference.

Every date and time in a response is in UTC too.

## Formats

| Type | Format | Example |
|---|---|---|
| Date and time | `YYYY-MM-DD HH:mm:ss` | `2026-11-09 18:39:46` |
| Date | `YYYY-MM-DD` | `2026-11-09` |

## Converting to and from UTC

Convert local times to UTC before you send them. For example, a meeting at 14:00 in a time zone that is UTC+2 is sent as `12:00:00`.

Convert the other way before showing a date or time to people.
