The date picker for work packages were updated in versions 12.2 and 12.3. There are however other views in OpenProject where date pickers exist and that are currently implemented differently than on work packages.

This feature seeks to list all of these different views, and propose a standardised "date-only" date picker that looks and behaves the same as the date picker for work packages.

### Identified views

* **Log time** (from work package, from My Saved view, when editing previously logged time)
* **Log unit cost** (from work package, when editing previously logged unit cost)
* **Work package and project custom fields**
* **Meeting minutes**
* **Single non-working days**
* **Pause date reminders**
* **Work package table filters**
* **Dynamic forms**
* **Work package move form**
* **Work package bulk edit form**
* **Announcement edit form**
* **Version new & edit form + custom fields**
* **Project filters**
* **Cost report filters**
* **Backlog edit**
* **Budget forms**

### Date-only picker

The date-only picker is a variation of the date picker for work packages (described in <mention class="mention" data-id="42047" data-type="work_package" data-text="#42047">#42047</mention>):

* It behaves like a drop modal.
* In mobile, the drop modal takes the full-screen (and effectively behaves as a normal modal). This can cause double-layering in some cases; this is acceptable.
* It doesn&#39;t have the scheduling or banner bits.
* It is otherwise the same as the simple date picker used in mobile.
* There is the option to add additional input fields on top of the date if needed, for example:
* Text fields
* Repeated date field (if the item calling the date picker isn&#39;t an input field)
* The toggle of &quot;Working days only&quot; is not enabled by default but can be added where Begin of the insertionrelevant. 
* End of the insertion Begin of the deletion relevant.End of the deletion For 12.5, they will only be enabled in these places: Begin of the insertion
End of the insertion Begin of the deletion
End of the deletion * Log time Begin of the insertion

End of the deletion * Cost report filter Begin of the insertion
End of the insertion Begin of the deletion
End of the deletion * Budget forms Begin of the insertion
* When the toggle is displayed, it is _ON_ by default.End of the insertion
* The logic and behaviour follows the current implementation in <mention class="mention" data-id="42047" data-type="work_package" data-text="#42047">#42047</mention>.

### Out of scope

* The fact that the currently used date picker (the default Flatpickr one), has week numbers whereas the &quot;new&quot; OP one does not. Some clients have requested this to be reinstated; this is being tracked in <mention class="mention" data-id="35329" data-type="work_package" data-text="#35329">#35329</mention>.
