1. Example.

I desire to know at what time in the Turkish Account, the fifth of Iune in the year of our Lord 1640. doth fall.

The Julian years complete are 1648, and are thus turned into days, by the Table of days in Julian years.

1000 Julian years give days
365250
600 Julian years give days▪
219150
40 Julian years give days
14610
8 Years give days
2922
May complete
151
Days
5
The Sum is
602088

Now because the Turkish Account began Iuly 16. Anno Christi. 622. you must convert these years into days also.
