%description
Jalali, also known as Persian, Solar Hijri and Hijri Shamsi calendar is
the official calendar of Iran and Afghanistan. It begins on Nowruz, the
March equinox, as determined by astronomical calculation and has years of
365 or 366 days. Adapting the algorithms in <https://jdf.scr.ir/>, this
package provides tools for converting the Jalali and Gregorian dates.
