%description
The Jalaali calendar, also known as the Persian or Solar Hijri calendar,
is the official calendar of Iran and Afghanistan. It starts on Nowruz, the
spring equinox, and follows an astronomical system for determining leap
years. Each year consists of 365 or 366 days, divided into 12 months. This
package provides functions for converting dates between the Jalaali and
Gregorian calendars. The conversion calculations are based on the work of
Kazimierz M. Borkowski (1996) (<doi:10.1007/BF00055188>), who used an
analytical model of Earth's motion to compute equinoxes from AD 550 to
3800 and determine leap years based on Tehran time.
