ID Timestamp Extractor
Most modern ID schemes embed their creation time. Paste a UUID (v1/v6/v7), ULID, MongoDB ObjectID, KSUID or Snowflake ID and get the timestamp back — format is detected automatically.

What can be decoded?
| Format | Looks like | Timestamp precision |
|---|---|---|
| UUID v7 | 0190a4d2-55e3-7… | milliseconds (first 48 bits) |
| UUID v1 / v6 | c232ab00-9414-11ec-… | 100 ns since 1582 (Gregorian) |
| ULID | 01HZYQ3E8PXJ… (26 chars) | milliseconds (first 10 chars) |
| MongoDB ObjectID | 65d4f8a1e4b0… (24 hex) | seconds (first 4 bytes) |
| KSUID | 0ujtsYcgvSTl8… (27 chars) | seconds since 2014-05-13 |
| Snowflake (Twitter/X, Discord) | 1747504640632741888 | milliseconds since custom epoch |
| UUID v3 / v4 / v5 / v8 | random or hashed | no timestamp embedded |
