I would like that the date picker in Confluence shows week numbers, just like the date picker in Jira does.

Date picker in Confluence:

Date picker in Jira:

This would help a lot when selecting dates, since week numbers (and day of the week) are widely used in our company - much more than dates. Therefore, as it is now, when people want to set a date in Confluence they have to switch to another app (e.g. to the Outlook calendar) to see week numbers and what dates that correspond to each week, and then switch back to Confluence again to set the date. This is inconvenient for the end users.
