The Shaka era (IAST: Śaka, Śāka) is a historical Hindu calendar era (year numbering), the epoch (its year zero)[2] of which corresponds to Julian year 78.

^Like most Indian eras, the Śaka era uses expired, elapsed, or complete years, where a year must have elapsed before it can be counted. This is similar to the Western method of determining a person's age, whose first year must have been completed before that person reaches one year old. The uncounted first year of the era is numbered as year zero. This differs from Western eras which use current years.[1]
