note-1: Saka calendar is used in India for civil purpose as well as Gregorian calendar.
Year 1954-55 A.D. corresponds 1876 Saka, 1954 A.D. corresponds 1875-76 Saka
Year starts from the day following the vernal equinox day.
After adding 78 to the Saka Era, if the sum is divisible by 4. then it is a leap year
(Saka calendar is not very popular as compared to Western calendar)
note-2: Use SM (Sebelum Masehi) in place of BC. SM is same calendar as BC, but different in name
note-3: Japanese Era: Japanese Era name changes from Emperor to Emperor. Heisei is current Era, and Showa, Taisho and Meiji had been used for the past 100 years.
Era name changes at the first day of Emperor, therefore, the ending year of one Era is the starting year of following Era (In sense of AD, one year has two Era names). Those two years are not full year,
for example, year of Showa 64 is only 6 days a year (and year of Heisei 1 for the rest).
