Tarabala works out whether today is a good day for you by counting nakshatras from the one the Moon was in at your birth to the one it is in now.

The count runs one to nine and then repeats, and each position has a name and a verdict — the fourth is obstruction, the seventh is danger, the ninth is the friend. It is a personalised daily reading that requires no chart, no software and no astrologer, only two numbers, which is a large part of why it survived.
