How to interpret the result
Check the Moon's degree in the graha table before quoting your Rashi. In a constructed chart, the Moon at 29.7 degrees of sidereal Taurus gives a Taurus Rashi, yet a Western chart for the same moment would show the Moon around 23 to 24 degrees of Gemini. Because that Moon sits only 0.3 degrees from Gemini, a birth roughly half an hour later would make the Rashi Gemini too, so the sign stays provisional until the time is confirmed.
Why it matters
Jyotish leans on the Moon sign for daily forecasts, transit counting and compatibility, while Western practice leads with the Sun. This page helps someone who has only known a Western Sun sign find the sign a Vedic reader will ask about.
Traditional meaning
The tradition links the Moon, Chandra, with the mind and with how experience is taken in, so the Rashi is read as the emotional climate of a chart. Many readers also count houses from it, a frame called Chandra Lagna, as a second viewpoint beside the rising sign.
Reflection use
Read a week of commentary arranged by your Rashi beside one arranged by your Western Sun sign, and note which lines feel like observations and which like padding. Treat it as a record of how two systems frame you, not a test of either.
