Welcome to the IgboKal Time-Sound Converter

A tool that translates Gregorian dates into the Igbo temporal system known as the year-count or Ọgụ Afọ.

Here we convert time into sound; and orient sound as time. The Igbo 364-day Kalendar — 13 months, 4 market days, 91 Izu — each carrying a frequency, a tone, a vibration that connects the seen to the unseen. The Ọgụ Afọ Time-Sound abacus is the supreme grounding/balancing mechanism for our age.

Know Your Day

Enter any date and discover where it falls on the sacred ring. Your month, your market day, your Izu cycle, your Igboan Year — all revealed in the language of the ancestors.

Hear the Year

Each of the 13 months has its own sound — a unique note in a scale built from the Igbo year. The root note beats once for every day of the year — 364 heartbeats. Listen, and let the sound ground you.

Find Your Chi

Set your birth date to discover your Chi Phase — your position on the yearly cycle. When your current position aligns with your origin, you experience Solar Chi Return: a moment of renewal.
