Abstract

The shuhūr sanah, also called the Shuhur era, was a solar calendar used in Deccan India in the pre-modern and early modern periods. Scholars have long assumed that the calendar was instituted in the early fourteenth century, sometime in 1344–1345 CE, although, to date, no primary evidence from the fourteenth century has been examined to substantiate this inaugural date or explain the circumstances that led to the genesis of the calendar. In the present article, I discuss a 1333–1334 CE Persian epigraph from Daulatabad that uses the phrase shuhūr sanah and argue that the calendar was instituted during a period of economic, administrative, and agricultural uncertainty in the reign of the Delhi Sultan Muhammad bin Tughluq (r. 1325–1351). In so doing, I re-date the inauguration of the calendar to a decade prior to what has been assumed thus far and posit a new theory about the calendar’s longevity in the Deccan. More broadly, I examine the historiography and the historical usage of the Shuhur era in the Persianate epigraphic corpus. The survey reveals how the Shuhur era was used to make public-facing pronouncements and also clarifies the limits of the calendar’s usage. The calendar was popular in the late sixteenth and early seventeenth centuries; after this period, it was phased out by other calendrical systems preferred by the Mughal (1526–1857) and the Maratha (1674–1818) empires, who came to control the Deccan.
