Unix Timestamp Converter
Convert epoch Unix timestamps (seconds & milliseconds) to human-readable dates, or pick a date to generate corresponding Unix timestamps instantly.

What is a Unix Timestamp?
The Unix epoch (or POSIX time) tracks time as the total number of elapsed seconds since 00:00:00 UTC on 1 January 1970 (excluding leap seconds). Because it represents a uniform scalar number independent of time zones, it is widely used across operating systems, database fields, and API payloads.
Common Code Examples
| Language / Environment | Get Seconds Epoch | Get Milliseconds Epoch |
|---|---|---|
| JavaScript / Node.js | Math.floor(Date.now() / 1000) |
Date.now() |
| C# / .NET | DateTimeOffset.UtcNow.ToUnixTimeSeconds() |
DateTimeOffset.UtcNow.ToUnixTimeMilliseconds() |
| Python | import time; int(time.time()) |
import time; int(time.time() * 1000) |
| SQL (PostgreSQL / MySQL) | SELECT EXTRACT(EPOCH FROM NOW()); |
SELECT UNIX_TIMESTAMP() * 1000; |

Using Unix Timestamp Converter in a development workflow
Choose the source and destination formats deliberately. Similar-looking data can have different escaping, precision, or null-value rules after conversion.
Check the source and target formats
- Run a small sample that includes punctuation or non-ASCII text so you can spot escaping and encoding changes before using larger input.
- Pay attention to these page fields: Enter Unix Timestamp, UTC Time, Local Browser Time. Confirm which fields are inputs, options, or output areas before processing.
- The page exposes these relevant actions: Use Current Time, Pause. Choose only the action that matches the result you need.
- Compare the converted value with the original, especially for escaping, character encoding, precision, and empty fields. Keep a copy of the source until the destination accepts the result.
Look for changes that affect your data
Formats can represent types, dates, empty values, comments, and numeric precision differently. Inspect a representative output instead of assuming conversion is lossless.
