Birth Time Explorer
Move the birth time second by second and watch the Lagna, Navamsa and D60 ascendants change, or turn any house into the 1st to read the chart from there. Built for time rectification and for studying a single bhava.
Birth time
Read the chart from
Tap a house in the chart, or pick one above, to make it the 1st house. Signs and planets stay where they are; only the house numbering moves.
Ascendant at this moment
| Chart | Lagna | Holds from | Until | Left |
|---|
The times show when each ascendant begins and ends around this moment, so you can see how much of the time window gives a particular Lagna, Navamsa or D60.
Ascendant timeline
Each row is the rising sign in that chart over time. Click or drag across it to move the birth time. The dashed line is the time you entered.

Vimshottari Dasha
The dasha at birth depends on exactly where the Moon is in its nakshatra, so a few minutes of birth time move every date below. Compare them with known life events.
Marked times
| Time | Lagna | D9 | D10 | D60 | Dasha at birth |

Mark the candidate times you are weighing and compare them side by side. Tap a row to jump back to it.
How to use it
Rectifying a time. Enter the birth details you have, then drag the slider or use the step buttons. The Lagna sign changes about every two hours, the Navamsa about every thirteen minutes and the D60 about every two. Mark the times that fit the person’s life and compare their dashas.
Studying one bhava. Choose a house under “Read the chart from” to make it the 1st: the 7th for partnership, the 10th for work, and so on. Planets and signs do not move, only the numbering does, and the table lists every house from there with its lord.
About the numbers. Positions are computed from planetary theory (VSOP87 and a lunar theory), sidereal by the Lahiri ayanamsa, with whole-sign houses. They are accurate to a small fraction of a degree, which is what sign, nakshatra and divisional placement need, but the divisional charts beyond D9 follow the common Parashari rules and differ between schools. This is a calculation aid, not a substitute for a qualified astrologer’s judgement.
