Try a worked example

Example

Choose Discord and enter 175928847299117063. The Unix timestamp is 1462015105796 milliseconds, with worker ID 1, process ID 0 and sequence 7. The displayed date uses your local time zone.

Keep in mind

Choose the epoch for the service that issued the ID; Twitter and Discord use different starting dates. Decoding the bits does not confirm that an account, message or other object exists.

About this tool

Decode 64-bit snowflake IDs into their embedded timestamp and machine fields using BigInt math, all in your browser.

Frequently asked questions

What is a snowflake ID?

It is a 64-bit ID where the high bits hold a timestamp (offset from a custom epoch) and the low bits hold worker, process and sequence numbers.

Which epoch should I pick?

Use the Twitter epoch (2010) for Twitter/X IDs and the Discord epoch (2015) for Discord IDs, since they timestamp differently.
