# UpdatePersonalTime
<a name="rest-op-updatepersonaltime"></a>

Replaces a personal time entry that you already created. You must sign in.

**Note**  
This replaces the entry. It does not merge. Resend every field, even the ones you are not changing. For the field list, see [Personal time fields](rest-op-createpersonaltime.md#rest-personal-time-fields). If you omit `location`, it is cleared. The entry keeps its `personalTimeId`.

```
PUT /v1/events/{eventId}/personal-time/{personalTimeId}
