52. The rules of both Makaranta and Thandeikta commence with the calculation of hnit-bo and yet-bo. Hnit-bo are the total lunations, with fraction, and total days, with fraction, expired at the moment when a given solar year ends, and the day of the week on which solar new year's day falls. Yet-bo are similar figures for midnight of any given day in any given year.
53. In this chapter the following symbols are used:—
| R | represents Ratha or Hnit kywin. |

| AT | represents„ Adimath thetha. |
| T | represents„ Thokdadein. |
| m | represents„ the expired months of the current year, counting from and including Tagu. |
| n | represents„ the given day of the month. |
54. Thandeikta calculations start from 1100 B. E. Thagayit − 1100 = Ratha. Makaranta calculations stare from 0 B. E., Poppasaw's epoch. But there is a second Makaranta method, starting from 798 B. E., the epoch of Mohnyin, King of Ava. Thagayit − 798 = Ratha by this method.
55. By Thandeikta, the total days expired at the end of the year R are
292000 is the kymmat of 365 days, 207 is the kyammat of 15 nayr 31 bizana
