The Gregorian calendar was introduced to correct the errors of which earlier calendar?
- A.The Julian calendar
- B.The Saka calendar
- C.The Hijri calendar
- D.The Vikram Samvat
Correct answer
Explanation
The correct answer is A, the Julian calendar. The Julian calendar, in use from 46 BC, assumed a year of exactly 365.25 days, which is about eleven minutes longer than the true tropical year of roughly 365.2422 days, so it gained a day about every 128 years and the equinox slid out of place. Option B, the Saka calendar, is a solar calendar of Indian origin counted from 78 AD and adopted as India's national calendar in 1957; it had no part in the European reform. Option C, the Hijri calendar, is the Islamic lunar calendar of 354 or 355 days counted from 622 AD, and because it is lunar it does not track the seasons at all. Option D, the Vikram Samvat, is the Indian lunisolar era counted from 57 BC. Only the Julian calendar was the direct predecessor of the Gregorian.
