Unix Timestamp Converter — Epoch to Date & Date to Epoch
Translate computer time to human time. Convert Unix timestamps (seconds or milliseconds since 1970) into readable dates, and vice versa. Essential for debugging server logs and database records.
How to use Unix Timestamp Converter
- Choose your conversion type — Decide if you want to convert a Timestamp to a Date, or a Date to a Timestamp.
- Enter your data — Paste a timestamp (e.g., 1735689600) into the input field, or use the date/time pickers to select a specific calendar date.
- Select seconds vs milliseconds — The tool auto-detects 10-digit (seconds) vs 13-digit (milliseconds) timestamps. You can manually toggle this setting if needed. JavaScript typically uses milliseconds, while PHP/MySQL use seconds.
- Review and copy formats — The tool instantly displays the result in multiple formats: UTC, your local timezone, ISO 8601, and relative time (e.g., "2 years ago"). Click Copy next to the format you need.
Features
- Bidirectional — Date to Timestamp / Timestamp to Date.
- Auto-detect — Guesses seconds vs milliseconds.
- Relative time — "2 hours ago".
Frequently Asked Questions
What is a Unix timestamp and why is it used?
A Unix timestamp (also called Epoch time or POSIX time) is a tracking system that represents time as the total number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC (excluding leap seconds). It is widely used in computing, databases (like MySQL), and APIs because it represents a single point in time securely as a simple integer. This makes it incredibly easy for computers to sort logs, calculate time differences, and completely bypasses complex timezone math.
What is the Year 2038 problem (Y2K38)?
Similar to the Y2K bug, the Y2K38 problem relates to how computers store the timestamp integer. Historically, Unix timestamps were stored as 32-bit signed integers, which have a maximum value of 2,147,483,647. At precisely 03:14:07 UTC on January 19, 2038, the clock will exceed this maximum value and physically "roll over" to a negative number (representing the year 1901), causing older systems to crash. Modern systems solve this by upgrading to 64-bit integers, which will not run out for another 292 billion years.
Why does my timestamp show the wrong time?
The two most common reasons are: 1) **Seconds vs. Milliseconds mix-up:** Some languages like PHP use 10-digit timestamps (seconds), while JavaScript natively uses 13-digit timestamps (milliseconds). If your date shows up in the year 56,000+, you likely fed milliseconds into a seconds parser. 2) **Timezone confusion:** Keep in mind that a Unix timestamp is inherently UTC. It has no timezone. The "wrong time" usually happens when an application strictly converts that UTC integer into the user's local timezone unexpectedly.
