What the Western tools need

The public sky page works without a birth profile. Personal tools become more accurate when you provide birth date, time and place in one complete entry flow.

Date

Required for every personal chart

Time

Best for Rising sign, houses and timing

Place

Sets timezone, latitude and longitude

Tropical zodiac

Western pages stay tropical. Vedic pages stay sidereal, so the systems remain clear.

Modern and traditional lenses

Natal reads use the modern psychological lens; Traditional Dignities keeps the classical strength-and-sect lens separate.

NASA/JPL DE engine

ModernAstro computes Western and Vedic tools with the same in-house NASA/JPL DE engine.
