Why does this tool use BigInt instead of regular numbers?

Snowflake IDs are 64-bit integers, and current values (around 10^18) far exceed JavaScript's safe integer limit of about 9 x 10^15. Using regular numbers would silently corrupt the ID during parsing. BigInt performs exact integer arithmetic regardless of size.

Can I decode a Snowflake ID from a platform other than Discord or Twitter?

Yes, if you know the platform's epoch (the reference date its Snowflake IDs count from). Select 'Custom' and enter that epoch as a Unix millisecond timestamp; this tool assumes the same 22-bit shift used by Twitter and Discord.

Overview

What is a Snowflake ID?

A Snowflake ID is a 64-bit unique identifier design originated by Twitter, later adopted (with variations) by Discord, Instagram, and other large-scale platforms.

The top bits encode a millisecond timestamp relative to a platform-specific epoch, so IDs sort chronologically and any client can extract "when was this created" without a database round-trip.

64-bit integer, sortable by creation time
Top 41-42 bits: milliseconds since a platform epoch
Bottom 22 bits: worker/process ID and per-ms sequence
Discord epoch: 2015-01-01 · Twitter/X epoch: 2010-11-04

Shift right by 22 bits, then add the platform's epoch to get the timestamp.

How do I find out when a Discord account or message was created?

Paste the user, message, server, or channel ID into the decoder above with "Discord" selected — the exact creation timestamp is extracted instantly, since Discord IDs are Snowflake IDs with the creation time built in.

FAQ

Frequently Asked Questions

A Snowflake ID is a 64-bit unique identifier format, originally designed by Twitter, that embeds a timestamp directly in the ID. This makes Snowflake IDs sortable by creation time without a database lookup. Discord, Instagram, and other large platforms use variations of the same design.

Paste the ID (from a user, message, server, or channel) into this decoder and select "Discord" as the platform. The timestamp is extracted by shifting the ID right by 22 bits and adding Discord's epoch (January 1, 2015).

Snowflake IDs are 64-bit integers, and current values (around 10¹⁸) far exceed JavaScript's safe integer limit of about 9 × 10¹⁵. Using regular numbers would silently corrupt the ID during parsing. BigInt performs exact integer arithmetic regardless of size.

Yes, if you know the platform's epoch (the reference date its Snowflake IDs count from). Select "Custom Epoch" and enter that epoch as a Unix millisecond timestamp; this tool assumes the same 22-bit shift used by Twitter and Discord, which most Snowflake variants share.
