Changing the first day of the week in the log‑time Date picker

Question

Would it be possible to modify the “Date” attribute in the log-time form? For example, can the date picker be configured so that the calendar displays Monday as the first day of the week instead of Sunday?

Answer

To update the date picker in Tempo, enable the “Use ISO8601 standard” option by following these steps:

  1. Go to Jira Settings

  2. Select System

  3. Click Look and Feel

  4. Check the option “Use ISO8601 standard”

This setting will configure the date picker to display Monday as the first day of the week instead of Sunday.
