01. Check the details on your birth chart.
Your birth date, exact time and place are used to establish the Moon’s position and the planetary periods active at birth. An accurate time is important in the author’s method.
The trial calculator can work from your birth details. Search for your city and select the right place so we can apply the timezone in effect when you were born. It uses Lahiri settings and is labelled as a trial.
02. Find three things in your chart.
Look for the Moon, sometimes labeled Mo or Chandra. Beside it, find your Janma Nakshatra and the three Vimshottari periods at birth.

Use the full planet names in our form. The shorthand is retained in results for anyone who prefers it.

03. Read the observations in context.
Exact matches share your current nakshatra group and all three birth periods. Broader matches share the first two periods but have a different third period. They are shown in separate views.
Ages belong to the original research subjects. When you supply a birth date, the app projects those ages onto your calendar as approximate dates. A year-and-month source never becomes an exact-day prediction.
If a combination is missing, that is a gap in the archive. It does not imply anything about your life.
