Add Solar Hijri calendar
It would be great if we can use Solar Hijri calendar in SP without depending (expense and support) on 3rd parties.

Hijri Calendar in Windows 10 is very good and we want from Microsoft Corporate add this calendar in Microsoft SharePoint 2016 (or later) and Microsoft Project and Microsoft Dynamic.

Yes, It would be great if Microsoft support Persian Language and Calendar for both SharePoint on-premise and Online version.
