Iran's Health after A Hundred Years: Snapshots of the Beginning and End of the Solar Hijri Century.

Iranians live by the Solar Hijri (SH) calendar. The starting point of this calendar, much like the Lunar Hijri calendar (which is the basis of religious practices in Islamic countries), is the Islam Prophet's migration. The origin of this particular calendar is on the earth's rotation around the Sun instead of the moon. On March 21, 2022, the year 1401 SH (Iranian calendar) was begun, and the 14th century of SH was ended. During the last SH century, from 1301 to 1400 SH (1922-2022 AD), Iran’ health has experienced various changes.
