• Unix timestamp represents seconds elapsed since January 1, 1970, 00:00:00 UTC
• Commonly used in programming, databases, and APIs for date/time storage
• This converter supports both 10-digit (seconds) and 13-digit (milliseconds) timestamps
• All conversions are performed in your local timezone
About Epoch Converter
Convert Unix timestamps (epoch time) to human-readable dates and vice versa. Unix time is the number of seconds since January 1, 1970 UTC—the format computers use internally to track time.
Timestamps show up everywhere in programming: APIs, logs, databases, JWT tokens. This tool converts between the number format computers understand and the date format humans can read, handling both seconds and milliseconds.
How to use Epoch Converter
Paste a Unix timestamp (like 1705084800) to convert to a date.
Or pick a date to get its Unix timestamp.
Check if your timestamp is in seconds (10 digits) or milliseconds (13 digits).
See the result in your local timezone and UTC.
Copy the converted value.
Examples
Seconds vs milliseconds
The most common mistake—using seconds when milliseconds are expected or vice versa:
Seconds (10 digits): 1705084800 → January 12, 2024 8:00:00 PM UTC Milliseconds (13 digits): 1705084800000 → January 12, 2024 8:00:00 PM UTC JavaScript uses milliseconds: Date.now() → 1705084800000
Common timestamps
Reference points for sanity checking timestamps:
0 → January 1, 1970 (Unix epoch) 1000000000 → September 9, 2001 1500000000 → July 14, 2017 2000000000 → May 18, 2033 (future!) If your date shows 1970, you probably have 0 or null
Timezone handling
Unix timestamps are always UTC. Your display depends on timezone:
Timestamp: 1705084800 UTC: Fri Jan 12 2024 20:00:00 US Eastern: Fri Jan 12 2024 15:00:00 (UTC-5) India: Sat Jan 13 2024 01:30:00 (UTC+5:30) Tokyo: Sat Jan 13 2024 05:00:00 (UTC+9)
