 However, Yukio Ohashi considers this proposal as incorrect, suggesting instead that the Vedic timekeeping efforts, for forecasting appropriate time for rituals, must have begun much earlier and the influence may have flowed from India to Mesopotamia.Ohashi states that it is incorrect to assume that the number of civil days in a year equal 365 in both Hindu and Egyptian–Persian year.Further, adds Ohashi, the Mesopotamian formula is different from the Indian formula for calculating time, each can only work for their respective latitude, and either would make major errors in predicting time and calendar in the other region.
