116. In compliance with a desire expressed by many persons interested in the *Drig-ganita* system, it has been thought advisable to include in the present work three very simple tables (XVI-A, XVI-B and XVI-C) for correcting the ending moments of *tithis* worked out according to the *Sûrya-Siddhânta*, so as to bring them within 2 ghaṭikas of *Drig-ganita* or *Nautical Almanac* results, further approximation not being possible within the limits of a popular work. Seeing that Siddhânta and *Drig-ganita* *panchângams* occasionally exhibit a divergence of 17 ghaṭikas (7 hours) in regard to *tithis* intermediate between new-moon and new-moon, the approximations now made possible will go a great way towards leading to a better understanding between the followers of the two systems.
