# Epoch Converter

> A free online tool to convert Unix epoch timestamps to human-readable dates and vice versa. No signup required.

## What This Tool Does

Epoch Converter converts between Unix epoch timestamps (seconds since January 1, 1970 UTC) and human-readable date formats. It supports multiple timezones, millisecond and second precision, and provides instant conversion with no server round-trip. Everything runs client-side in the browser.

## Features

- Convert epoch timestamp (seconds or milliseconds) to human-readable date
- Convert human-readable date to epoch timestamp
- Live epoch clock showing current Unix time updated every second
- Duration converter: seconds to days/hours/minutes and reverse
- Timezone converter with 22+ timezones and world clock
- Code examples for epoch conversion in JavaScript, Python, PHP, SQL, Java, Go
- Copy-to-clipboard on all values
- Educational content explaining Unix epoch time, its history, and the Year 2038 problem
- Trivia table of notable epoch milestones

## Key Facts About Epoch Time

- Unix epoch time counts seconds since January 1, 1970, 00:00:00 UTC
- It is timezone-independent — always based on UTC
- 32-bit systems will overflow on January 19, 2038 at 03:14:07 UTC (the Year 2038 problem)
- Modern 64-bit systems store epoch time safely for ~292 billion years
- Common values: 1 hour = 3,600s, 1 day = 86,400s, 1 year ≈ 31,536,000s

## How to Convert Epoch Time

### JavaScript
```javascript
const date = new Date(1700000000 * 1000);
const epoch = Math.floor(Date.now() / 1000);
```

### Python
```python
from datetime import datetime
import time
date = datetime.fromtimestamp(1700000000)
epoch = int(time.time())
```

### PHP
```php
$date = date('Y-m-d H:i:s', 1700000000);
$epoch = time();
```

### SQL (MySQL)
```sql
SELECT FROM_UNIXTIME(1700000000);
SELECT UNIX_TIMESTAMP();
```

## Frequently Asked Questions

- **What is Unix epoch time?** — The number of seconds elapsed since January 1, 1970, 00:00:00 UTC. Timezone-independent.
- **What is the Year 2038 problem?** — 32-bit signed integers overflow at 2,147,483,647 (Jan 19, 2038 03:14:07 UTC). 64-bit systems are unaffected.
- **Seconds vs milliseconds?** — Seconds = 10 digits, milliseconds = 13 digits. JavaScript uses ms, Python uses seconds. This tool auto-detects.
- **Is epoch affected by timezones or DST?** — No. Epoch is always UTC-based. Timezones only matter when displaying human-readable dates.
- **Does this tool send data to a server?** — No. Everything runs client-side in the browser. No API calls, no tracking, no cookies.
