📅 Date to Unix Timestamp Converter

How to Convert Date to Unix Timestamp

Converting a date to Unix timestamp is simple: select the date and time, then click Convert. Our tool generates both seconds (10 digits) and milliseconds (13 digits) formats, which you can use in any programming language or database.

Unix timestamps represent time as the number of seconds or milliseconds since January 1, 1970, 00:00:00 UTC (the Unix epoch). This format is universal across programming languages and databases.

Why Convert Date to Unix Timestamp?

• Database Storage: Store dates efficiently as integers
• API Development: Send timestamps in API requests and responses
• Time Calculations: Easily calculate time differences
• Scheduling: Set cron jobs and scheduled tasks
• Cross-Platform: Universal format works everywhere
• Performance: Faster comparisons than date strings

Code Examples

JavaScript

const date = new Date('2024-04-16T18:30:59'); const timestampSec = Math.floor(date.getTime() / 1000); const timestampMs = date.getTime(); console.log(timestampSec); // 1713293459 console.log(timestampMs); // 1713293459000

Python

import datetime date = datetime.datetime(2024, 4, 16, 18, 30, 59) timestamp = int(date.timestamp()) print(timestamp) # 1713293459

Common Use Cases

• Event Scheduling: Convert event dates to timestamps for storage
• Expiration Times: Set token or session expiration timestamps
• Log Timestamps: Generate timestamps for log entries
• Date Comparisons: Compare dates by converting to timestamps
• API Integration: Send dates as timestamps to third-party APIs

Frequently Asked Questions

Should I use seconds or milliseconds?

Use seconds (10 digits) for PHP, Python, and Unix systems. Use milliseconds (13 digits) for JavaScript, Java, and modern APIs that need millisecond precision.

How do I convert Unix timestamp back to date?

Use our Unix Timestamp to Date converter to convert timestamps back to readable dates.

What timezone is used?

The converter uses your local timezone by default. Unix timestamps are always stored in UTC, but the conversion accounts for your timezone offset.
