know about Panchangam
On the new year day the Panchangam is read to learn about what the ensuing year has in store for us. The Panchangam essentially consists of five parts of the day, viz., the name of the day, the tithi of the day, the star of the day, the yogam of the day, and the karanam of the day.
Starting any new venture on the appropriate tithi will fetch iswaryam (lots of wealth and prosperity) for the person. Similarly, any deed done on the right day of the week will enhance the longevity, ie the life span of the person will increase.
