Sun Time

Our ancient ancestors observed that the height of the noon sun varies throughout the year of 365 days. By measuring shadow length at noon each day, accurate reckoning of the progress of the year could be determined and the first calendars were made.

How did early astrologers determine the vernal equinox? They may have looked out for the moon riding into the constellation of Libra. This would mean that the sun had entered into Aries. However due to the wobblng of the earth's axis over centuries, today's observers must look for the moon's appearance in the constellation of Virgo. Tropical astrology however continues to use the original zodiac - discounting precessional effect.

The next important date after the equinox is the solstice. There are two equinoxes and two solstices each year. Check the dates for each of them in the last decade 2010-2020.
