Unix Time Calculator

Formula: Converting Date to Unix Time

What Is the Unix Time Calculator?

The Unix Time Calculator is a practical online tool that helps you convert between standard date and time formats and Unix timestamps. Unix time, also called Epoch time, represents the number of seconds that have passed since January 1, 1970, 00:00:00 UTC. This calculator supports both directions: converting human-readable dates to Unix timestamps and converting timestamps back to readable date-time formats.

Why Use a Unix Time Calculator?

Whether you're logging data, scheduling tasks, or analyzing time intervals, this calculator helps simplify time-based conversions. It acts as a:

• Time difference tool to measure gaps between events
• Timestamp conversion tool for applications and databases
• Duration calculator for adding or subtracting time
• Time span converter when you need to work across time units like days or hours
• Time tracking helper for developers, analysts, and researchers

How to Use the Unix Time Calculator

1. Convert Date and Time to Unix Timestamp

• Select a date and time from the input field
• Click "Convert to Unix Timestamp"
• The result appears in seconds since the Epoch

2. Convert Unix Timestamp to Date and Time

• Enter a Unix timestamp (e.g., 1714822400)
• Click "Convert to Date"
• You’ll see the corresponding UTC date and time

3. View the Current Time

• Check real-time Unix timestamp and UTC date-time values
• This section updates every second automatically

4. Perform Unix Time Arithmetic

• Enter a base timestamp
• Choose to add or subtract
• Set a time value and its unit (seconds, minutes, hours, etc.)
• Click "Calculate" to get the resulting timestamp and readable date

Common Use Cases

This tool is ideal for:

• Converting Unix timestamps in databases or log files
• Working with APIs that return time in Unix format
• Creating time-based calculations in automation scripts
• Scheduling or comparing global events with UTC

Frequently Asked Questions

What is Unix time?

Unix time counts the number of seconds that have passed since January 1, 1970, at midnight UTC. It’s widely used in programming and systems as a consistent time format.

Why is Unix time useful?

It provides a simple, numeric format to represent time. It's especially useful in computing where consistent, timezone-independent timestamps are required.

Can Unix time go backward?

Yes, negative values represent times before the Unix epoch (before 1970).

What about milliseconds?

Some systems use Unix time in milliseconds. In those cases, multiply or divide by 1,000 as needed.

Does Unix time account for time zones?

No. Unix time is always based on UTC. You can adjust for time zones manually if needed.
