💡 Versions 1, 6, and 7 (and ULIDs) embed a creation time, which is decoded above. Versions 4 are fully random and carry no timestamp. Everything is parsed in your browser.

UUIDv7 tips

🕒

UUIDv7 stores a 48-bit Unix millisecond timestamp in its first bits — decoded here as a readable date.

📈

Because the time leads, v7 UUIDs sort chronologically, which is great for database keys.

🔍

Handy for debugging: see exactly when a record with a given v7 ID was created.

🔒

The ID never leaves your browser.
