I'm new to Odoo.
There are some out-dated apps at Odoo app store and I tested some of them and they didn't worked in Odoo 12.
I found out that Odoo uses moment.js for dealing with dates. I found moment jalali for converting Gregorian date to Jalali date but I don't know how to use it in Odoo.
Is there another way to change dates, calendars and datepickers from Gregorian to Jalali ?
