           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs@lists.freedesktop.org

Jalali (Hijri Shamsi, or Solaro Hijri) is the calendar used in Iran and
Afghanistan. It shares the same epoch (start date, Hijra) with the (Lunar)
Hijri calendar which is available in Libreoffice as
i18npool/source/calendar/calendar_hijri.cxx. The difference is that the Jalali
calendar uses solar years.

An introduction to Jalali calendar can be found here:

Currently, people may use a macro to be able to use Jalali Calendar, but it has
its own shortcomings:

A good FOSS implementation of Jalali calendar is available in C programming
language without extra dependencies:

It has been used in Ubuntu, Debian and elsewhere:
https://packages.ubuntu.com/bionic/utils/jcal
https://packages.debian.org/sid/jcal
