What is a Twitter Snowflake ID?

Twitter uses snowflake IDs - unique 64-bit identifiers for tweets, users, direct messages, and other objects. These IDs encode the creation timestamp, making it possible to extract the exact date and time when a tweet was posted or account was created.

Example Twitter ID: 1382350606417817604

This ID was created on: April 14, 2021 at 15:30:06 UTC

Step-by-Step: How to Decode Twitter Snowflake ID

1

Get the Twitter ID

Find the Twitter ID you want to decode. You can get it from:

Tweet URL: twitter.com/user/status/1382350606417817604
User profile API response
Direct message ID

2

Understand the Formula

Twitter snowflake IDs encode the timestamp in the first 42 bits. The formula to extract it:

timestamp_ms = (snowflake_id >> 22) + 1288834974657

Where:

>> 22 = Right bit shift by 22 positions
1288834974657 = Twitter epoch (Nov 4, 2010, 01:42:54 UTC)

3

Apply the Formula

Let's decode 1382350606417817604:

1382350606417817604 >> 22 = 329579231760 329579231760 + 1288834974657 = 1618414206417

Result: 1618414206417 milliseconds since Unix epoch

Convert to Human-Readable Date

Convert the Unix timestamp (1618414206417 ms) to a date:

Result: Wednesday, April 14, 2021, 15:30:06 UTC

Technical Details

Snowflake ID Structure (64 bits)

Bits 0-21 (22 bits): Sequence number and machine ID
Bits 22-63 (42 bits): Timestamp in milliseconds since Twitter epoch

Twitter Epoch

Twitter's custom epoch starts at: 1288834974657 milliseconds (November 4, 2010, 01:42:54 UTC)

Programming Examples

// JavaScript const TWITTER_EPOCH = 1288834974657n; const id = 1382350606417817604n; const timestamp = Number((id >> 22n) + TWITTER_EPOCH); const date = new Date(timestamp); // Python TWITTER_EPOCH = 1288834974657 id = 1382350606417817604 timestamp = (id >> 22) + TWITTER_EPOCH date = datetime.fromtimestamp(timestamp / 1000)
