The distinctive contribution of Haridatta, apart from his resolving the Aryabhatiya calculations and using the Katapayadi system of numerals is the corrections he introduced to the values of the mean and true positions, the velocity, etc., of the moon and other planets as obtained from Aryabhata's constants. This correction is called the Sakabda-samskara since it applied from the date of Aryabhata in the Saka era 444, at which date his constants gave accurate results.
