Timestamp & Timezone Converter

How to Convert Unix Timestamps

1. Enter a Unix timestamp (seconds or milliseconds) in the input field to see the human-readable date and time.

2. Or select a date and time to get the corresponding Unix timestamp.

3. Use the Timezone Converter to convert times across 30+ global timezones instantly.

Unix Timestamp Converter

Convert Unix timestamps (epoch time) to human-readable dates and vice versa. Unix time counts the number of seconds since January 1, 1970 00:00:00 UTC. It is the standard time format used by operating systems, databases, APIs, programming languages, and server logs worldwide.

Timezone Converter

Convert times between 30+ major timezones instantly. Essential for distributed teams, scheduling international meetings, debugging server logs from different regions, and understanding when events occurred in different parts of the world.

Common Unix Timestamps

• 0 = January 1, 1970 00:00:00 UTC (the Unix epoch)
• 1000000000 = September 9, 2001 01:46:40 UTC
• 1700000000 = November 14, 2023 22:13:20 UTC
• 2000000000 = May 18, 2033 03:33:20 UTC
• 2147483647 = January 19, 2038 — the Y2K38 problem for 32-bit systems

Seconds vs Milliseconds

Unix timestamps are typically in seconds (10 digits, e.g. 1712345678). JavaScript, Java, and some APIs use milliseconds (13 digits, e.g. 1712345678000). Our tool auto-detects the format based on the number of digits.

FAQ

What is a Unix timestamp? A Unix timestamp (or epoch time) is the number of seconds elapsed since January 1, 1970 at midnight UTC. It is timezone-independent, making it ideal for storing and comparing times across systems.

Why do developers use Unix timestamps? Because they are timezone-neutral, easy to compare mathematically, and take less storage space than date strings. All major programming languages can parse them.

How do I get the current Unix timestamp? In JavaScript: Math.floor(Date.now()/1000). In Python: import time; int(time.time()). In Bash: date +%s. Or just look at the live clock at the top of this page.

What is the Y2K38 problem? 32-bit systems store Unix time as a signed 32-bit integer, which overflows on January 19, 2038. 64-bit systems are not affected and will work for billions of years.
