Udaya Lagna means the zodiac sign rising on the eastern horizon. It changes through the day and is highly dependent on latitude, longitude, local sidereal time, and sunrise. That is why Udaya Lagna for Dispur can differ from another city even when both cities follow IST. The calculation uses Dispur's local coordinates (26.1433°N, 91.7898°E) rather than a generic all-India timing.

Use this Dispur Udaya Lagna page to follow the current rising sign and the upcoming Lagna windows for the day. In Vedic astrology, Lagna is important while choosing a starting moment because it describes the visible beginning of an activity. A city-specific Lagna table helps users avoid rough approximations and select a window that matches the actual place of work, ceremony, travel, or personal decision.
