Unix Timestamp Converter
Convert any Unix timestamp (seconds or milliseconds) to a readable date and time in any timezone. Convert dates back to Unix timestamps. Shows current timestamp live, updating every second.
Unix Timestamp Converter — Coming Soon
We are building a 100% client-side interface for this tool. In the meantime, use the method below.
📐 How to convert manually
You can quickly convert a timestamp in your browser console (F12) by typing:
new Date(1700000000000).toString()
Replace the number with your timestamp.
The SolveBar Unix Timestamp Converter converts any Unix timestamp to a human-readable date and time, and converts dates back to Unix timestamps. Shows the current timestamp live, updating every second — essential for developers and blockchain users.
What is a Unix timestamp?
A Unix timestamp is the number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC — called the Unix Epoch. It is the universal time standard used by databases, APIs, blockchain networks and operating systems worldwide.
Seconds vs milliseconds
Most Unix timestamps are in seconds (10 digits). JavaScript and many APIs use milliseconds (13 digits). The converter automatically detects which format you have pasted and handles both.
Blockchain and crypto use
Every Ethereum transaction, Solana block and smart contract event is timestamped with Unix time. This tool is essential for reading block explorers, decoding contract events and verifying transaction timing.
Frequently Asked Questions
What is the current Unix timestamp?
The live timestamp is displayed at the top of the tool, updating every second. You can copy it with one click.
How do I convert a timestamp to a date?
Paste the timestamp into the input field. The tool automatically detects seconds or milliseconds and shows the equivalent UTC and local date and time.
What is Unix epoch time?
The Unix epoch is January 1, 1970 at 00:00:00 UTC. All Unix timestamps count seconds from this point. Negative timestamps represent dates before 1970.
