THE CHRONOLOGICAL SYSTEMS OF GUJARAT
dates especially the lunar days, weekdays and nakșatras given in posterior works like Prabandhas can hardly be taken as historical, unless and until they are confirmed by reliable sources.
Among the eras used in Gujarat during this period, the Vikram Era is found to be of most common use, while new eras like the Simha Era and the Hijrī Era also appear in a few Sanskrit records of this period. The usage of mentioning the week-day along with the lunar days gets well established by this time.
(i) The Vikrama Era As noticed above, the use of the Vikrama Era was adopted in Gujarat during the last part of the Maitraka period and continued during the post.Mait4. The nakşatras given in these dates are mostly found incongruent
with the corresponding tithis, for instance, (1) Sam. 993, Așadha śu. di. 15, Aśvini, (ii) Sam. 150. (1052?). Śrāvana, śu. di. 11, Puş ya, (iii) Sam. 1120, Chaitra, ba. 7, Hasta, (iv) Sam. 1150, Pauşa, ba. di. 3, Śravana, (v) Sam. 1199, Kārttika, [ba?] di. 2, Hasta.
The nomenclature given in the results arrived at after additions of numbers of years, months and days to the specfic dates of the commencement of individual reigns clearly indicates that the dates given in the Prabandhas are named according to the system of Kārttikädi years and Amänta months, which is current in Gujarat since long. The following calculations would make this observation clcar. Sam.
1078 Jyestha śu.di. 12 add years
42, months 10, days Sam 1120 Caitra
ba. di. add years
months 8, Sam 1150 Pausa
ba. di. 2
