ZunaSync

Your name and birth date reduce to a handful of numbers.

ZunaSync shows you what they are and what each one means. Free, no account needed.

Use the name on your birth certificate. Accents, hyphens and apostrophes are fine.

Your full name and birth year never leave this device. Only your first name, birth month and day, and the resulting numbers go into the chart link.

How it works

  1. Letters become digits

    Each letter maps to a number from 1 to 9: A is 1, B is 2, up to I at 9, then the cycle repeats.

  2. Totals reduce

    Digits are added together until one digit remains. The Master Numbers 11, 22 and 33 are kept as they are.

  3. Six numbers, one chart

    Your five core numbers come from your name and birth date. Your Personal Day changes with the calendar.
