One of the main errors committed during Sarvatobhadra Chakra analysis is incorrect adoption of Janma Vaara (name of weekday).
In Vedic Jyotish, Vaara remains from one sunrise until the next sunrise. It changes only when sun rises. Midnight or 12 o'clock have no role here.

For example, India got freedom at midnight (00:00:00) on 15 August 1947. That was a Friday as per calendar. However, as per Vedic Jyotish, it was still Guruvara on progress as Sun had not risen. Hence, Guruvara must be taken as one of the Birth points in calculations, not Friday.

If you are born before sunrise, then your Janmavaara should be cautiously picked and used in calculations. For someone born on Monday at 4:25 AM when sunrise is 5:37 AM, correct Janma Vaara is Ravivar. The study of Vedhan by Grahas of the correct Tithi gives correct results.

As per Vedic Jyotish, you were born on Mangalvar. English calendar changes date as well as weekday at 12 o'clock midnight. So, they both operate differently. In Jyotish calculations, Mangalvar should be treated as your Janma Var.
