How much does your birth time matter?

How many minutes of birth time would change your rising sign, nakṣatra and planetary periods, from the precision you give. Only Patri shows this.

Your birth details

Old names work too: Bombay, Calcutta, Madras, Benares.
Also worth asking

How accurate does my birth time need to be?

The rising sign changes about every two hours, the Moon’s nakṣatra about every day, and planetary period dates shift a few days for every few minutes of birth time. Patri computes, for your chart, how far each can move within the precision you give, and marks the outputs that could change.

How Patri works it out

  1. The chart recomputed across your stated precision (to the minute, 15 minutes, an hour).
  2. Minutes to the nearest change of rising sign, and the rising signs possible in the range.
  3. How many days the period boundaries shift; which outputs are unstable.
