I Ching Hexagram Calendar
64 I Ching hexagrams, assigned by birth date — the real King Wen sequence, computed live for any day of the year.
Each of the 64 hexagrams governs a fixed ~5.7-day period of the year, starting with hexagram 1 (The Creative) at the winter solstice and running in King Wen sequence order through hexagram 64 (Before Completion). Traditional I Ching divination doesn't work this way at all — a hexagram is normally cast fresh for a specific question, by tossing coins or counting yarrow stalks, not read off a birth date. This calendar is a modern, evenly-spaced division of the year (one period per hexagram) built for a birthday reading, not an ancient divination method, and it's presented here honestly as that.
The 64 hexagrams themselves — their names, trigrams, and meanings — are real, centuries-old King Wen sequence content. The specific day-by-day calendar mapping one hexagram to your birth date is a modern convenience for this feature, not how I Ching divination has traditionally been done.

Unlock everything →No — traditionally a hexagram is cast fresh for a specific question, by tossing coins or counting yarrow stalks, not read off a birth date. This calculator assigns each of the 64 King Wen hexagrams to a fixed ~5.7-day slice of the calendar year, a modern convenience for a birthday reading, the same kind of thing this site's rune calendar does for the 24 Elder Futhark runes.
Yes — the King Wen sequence, its 64 hexagram names, and their trigram pairings are genuine, centuries-old reference content. What's modern here is only the specific day-by-day calendar mapping one hexagram to your birth date, not the hexagrams or their traditional meanings.
By your birth month and day alone (no year needed) — each of the 64 hexagrams governs a fixed period of the year, starting with hexagram 1 (The Creative) at the winter solstice and running through the King Wen sequence to hexagram 64 (Before Completion).
Every hexagram is built from two of the 8 trigrams (Qian/Heaven, Kun/Earth, Zhen/Thunder, Kan/Water, Gen/Mountain, Xun/Wind, Li/Fire, Dui/Lake), stacked as an upper and lower trigram. The combination is part of the hexagram's traditional meaning, e.g. Water over Fire for hexagram 63.
No — a real I Ching consultation answers a specific question at a specific moment, cast by chance (coins or yarrow stalks) rather than assigned by date. This tool is a fixed birth-date lookup for exploring the 64 hexagrams, not a substitute for an actual divination casting.
