Snowflake ID Decoder

Q: What is a Snowflake ID?

A Snowflake is a 64-bit, time-sortable unique ID invented at Twitter and used by Discord, Instagram and many others. The high bits hold a millisecond timestamp relative to a custom epoch; the low bits hold machine/worker and sequence numbers so IDs never collide.

Q: How do I find when a Discord account, server or message was created?

Copy its ID with Developer Mode enabled (right-click → Copy ID) and paste it here with the Discord preset. The creation time is encoded in the ID itself: (id >> 22) + 1420070400000 milliseconds.

Q: Can I decode a Discord message link?

Yes. Paste a link like https://discord.com/channels/SERVER/CHANNEL/MESSAGE and the decoder extracts and decodes the server, channel and message IDs separately.

Q: How do I generate a Snowflake ID for a date?

Use "Generate a Snowflake from a date". It returns the smallest ID for that moment and the largest ID in that second, which you can use as after/before or min_id/max_id bounds when paginating the Discord or Twitter APIs.

Q: Why does my ID decode to the wrong date?

Each platform uses a different epoch and bit layout. Make sure the preset matches where the ID came from, or choose Custom and enter the epoch (in Unix milliseconds) and bit layout of your own Snowflake generator.

Decode Discord, Twitter/X and Instagram Snowflake IDs into their creation date, worker/process fields and a bit-by-bit breakdown. Paste one ID per line or a Discord message link; it all runs in your browser.

Generate a Snowflake from a date

Build the smallest and largest possible ID for a moment in time (your local time zone) — handy for before/after or min_id/max_id pagination and for checking whether an ID is older than a date.

Snowflake ID layouts

Platform	Epoch	Bit layout (high → low)
Discord	`1420070400000` (2015-01-01 UTC)	42 timestamp · 5 worker · 5 process · 12 increment
Twitter / X	`1288834974657` (2010-11-04 UTC)	1 unused · 41 timestamp · 10 machine · 12 sequence
Instagram	`1314220021721` (2011-08-24 UTC)	1 unused · 41 timestamp · 13 shard · 10 sequence

How to decode a Snowflake by hand

Shift the ID right by the number of non-timestamp bits and add the platform epoch. For Discord: (id >> 22) + 1420070400000 gives Unix milliseconds. The official example 175928847299117063 decodes to 2016-04-30T11:18:25.796Z, worker 1, process 0, increment 7. IDs exceed JavaScript's safe integer range, so this tool uses BigInt to stay exact.

Finding Discord IDs

Enable Developer Mode in Discord (Settings → Advanced), then right-click a message, user, channel or server and choose Copy ID — or use Copy Message Link and paste the whole link here. To share a time in chat, use the Discord timestamp generator. For other time-sortable IDs see the ULID generator & decoder.
