Dear Bhante
Awareness of the seasons, the months, the days and of time is for me an important guideas well as pointer to the awareness of self and what I think and do.
Thanks for this detailed information.

Dear Bhante
I just chanced on this page. Lovely and engaging!
Might you have any idea as to when the lunar cycle was adjusted to fit into a seasonal solar one? I understand that Vesākha had in pre-Buddhist eras been simply the lunar month in which the full month transited through the Vesākha constellation.
Owing to the effects of the precession of the equinoxes, the position of the moon to the constellations would shift 1 degree every 71 years. In the 2500 years since the Buddha’s time, the shift would be a very noticeable 35 degrees. Vesākha today would definitely not mark the lunar month in which the full moon transits through the Vesākha constellation.
I’m told that the Indian astrologers were aware of the precession, thus giving a sidereal Indian calendar. Over time, an insistence on the sideral calendar would not have matched the seasonal solar calendar, eg the rains would arrive at the same season, regardless of where the moon was.
Do you have any idea when the Indians or the Buddhists gave up tagging the moon to the constellations, in favour of a seasonal solar calendar?
Many thanks, Bhante.
Hi Sylvester, glad to hear the post was of interest. According to this Wikipedia page they probably knew about the precession in Vedic times. In fact possibly the most advanced science was the understanding of the calendars in ancient times, as we can witness in many cultures.
Much obliged, Bhante.
