dates from the reign of Gházán* Khán and is founded on the Elkháni tables. The years and months are Natural, solar. Before its adoption the State records bore date from the Hijrah and the lunar year was current. By this means the road was opened to grievous oppression, because 31 lunar years are equal to only 30 solar years and great loss occurred to the agriculturists, as the revenue was taken on the lunar years and the har­vest depended on the solar. Abolishing this practice Gházán Khán promoted the cause of justice* by the introduction of this era. The names of the month are the Turkish with the addition of the word kháni. Of this, 293 years have elapsed.
