Why Use This Tool?
X (formerly Twitter) shows posts as '2h' or 'Mar 5' — useless when you need the exact moment. The trick: every post ID is a Snowflake, a number whose top bits encode the creation timestamp to the millisecond. This decoder does the bit-shifting for you.
Paste a full post URL or just the ID. You'll get the exact posting time in UTC and your local time zone, plus the Unix timestamp and the post's age in days. Nothing is sent anywhere — the math runs in your browser.
How It Works
- Copy the X post link, or the numeric ID from it.
- Paste it above and click decode — the Snowflake timestamp is extracted instantly.
- Read the exact posting time in UTC, your local time, and Unix form.
Frequently Asked Questions
How do I find the exact time of an X post?
Extract the numeric ID from the post's URL (the long number after /status/) and decode it here. The ID's top bits are the creation timestamp, accurate to the millisecond.
What is a Twitter Snowflake ID?
A 64-bit number X generates for every post: 41 bits of timestamp since November 4, 2010, plus worker and sequence bits. The timestamp is what this tool reads.
Does the decoded time show my time zone?
Both — you get the UTC posting time and your browser's local time zone rendering of the same moment.
Tips & Things to Watch
- Works with x.com and twitter.com status links alike.
- Great for verifying when a screenshot was really posted.
- Posts from before 2010 aren't Snowflakes — Twitter's early IDs won't decode.
