This calculator shows Graha Gochar—when the planet you chose enters each sign (rāśi), how long it stays there, and when it stations retrograde or direct—for the year and place you select. Times are computed astronomically for your latitude, longitude, and time zone. Key points: • Transit vs. birth chart: Gochar tracks movement through signs over months and years; a birth chart freezes planet positions at birth. • Location: Sign-boundary times and local civil times depend on the city you pick; another place on the same calendar date can differ. • Retrograde: Apparent backward motion changes entry times and how long the planet appears in each rāśi. • How to use it: Many readers combine Gochar with daily Panchangam and personal chart study. This tool is for learning and timing awareness, not medical, legal, or financial advice.
