Annual chart cast at the precise instant the Sun–Moon angular distance restores its natal value — i.e. the same lunar phase recurs in the corresponding sidereal solar arc. Sources: Sanjay Rath, PVR Narasimha Rao.
Birth details
Cycle number — the chart is cast at the N-th lunar-return moment after birth.
Lunar-return annual chart
Tithi Pravesha takes the natal Sun-Moon angular separation Δ (the natal tithi position to within ~12°) and locates the next instant in your N-th year when Δ recurs — restoring both the solar position and the lunar phase you were born under.
Compared with Varshaphala (solar return alone), Tithi Pravesha is a tighter anchor — useful for native-with-multiple-children/sibling/spouse-event readings where the lunar phase carries weight.
The algorithm follows Sanjay Rath’s Tithi Pravesha note and PVR Narasimha Rao’s Saptarishis Astrology essay: locate the solar return first, then bisect on the Sun-Moon difference within ±15 days until the natal Δ is matched to under a second.
