Astronomical dating vedas
An equinox in astronomy is that moment in time (not a whole day) when the center of the Sun can be observed to be directly above the Earth's equator, occurring around March 20 and September 23 each year.The one in March 20 is considered the spring equinox and the September equinox is the vernal equinox.
Some historians of the past even refuse to acknowledge that Rama and other characters from the Ramayana even existed.The problem with this is that they do not provide definitive dates in themselves, but provide dates with repetitious cycles unless additional information is taken into account.There are two equinoxes during the calender year: the spring equinox and the vernal equinox and are days when the light of the Sun will spend a nearly equal amount of time above and below the horizon at every location on Earth and night and day will be of the same length.It should be noted that the ancient Indians had a prefect method of time measurement. Vartak has thus attempted to calculate the dates of important incidents that occured during the Ramayanic Era. Genealogical links available from the Mahabharat and Puranas, Yuga calculations and some archaelogical findings also provide clues to the dating of the Ramayanic era.They recorded the 'tithis', days according to the nakshatra on which the moon prevailed, the months, the seasons and even the different Solstices. The correct astronomical records goes to show that Valmiki's has chronicled an account of a true story and also, that the an advanced time measurement system was known to the Hindus (Indians) atleast 9000 years ago. Vartak's celebrated book "Vastav Ramayan" for further reading. Also, literary references to the characters from the Ramayanic Era provide limits after which the Ramayan could not have occured.
