What is Budhaditya Yoga?
Budhaditya Yoga — from Budha (Mercury) and Aditya (the Sun) — forms when the Sun and Mercury are conjunct, sitting together in the same sign and house of the birth chart. It is one of the most common yet valued yogas, giving a sharp intellect, eloquence, learning, success and fame.
The role of combustion
Because Mercury always stays close to the Sun (never more than about 28° away), this conjunction is frequent. The decisive question is whether Mercury is combust — too near the Sun, its light overpowered. Classical texts say a non-combust Mercury lets the Budhaditya brilliance shine fully, while a combust Mercury makes it work in flashes. This checker measures the exact Sun–Mercury gap and flags combustion.
What you get
The checker computes your sidereal (Lahiri) chart, confirms whether the Sun and Mercury are conjunct, shows the house where the yoga expresses, and grades its strength from Mercury's combustion, dignity and house plus the Sun's dignity — with a clear factor-by-factor breakdown and a downloadable PDF.
