About Date Formats
Date formats vary widely across different systems, programming languages, and regions. This converter supports all major date formats including ISO 8601, RFC 2822, Unix timestamps, SQL DateTime, and regional formats. It automatically detects the input format and converts to all supported formats simultaneously.
If you need to convert epoch to time or convert Unix epoch to date, use our dedicated Epoch to Date Converter for direct epoch workflows.
Migration scenarios: Database date format migration and log timestamp troubleshooting.

ISO 8601, JSON, and SQL Date Conversion
Use this page when you need to convert ISO 8601 timestamps, JSON date strings, SQL DATETIME values, JavaScript milliseconds, or Unix timestamps. It is useful for API payload validation, ETL pipelines, log parsing, and cross-system date cleanup.
Convert Date to Epoch and Epoch to Date
You can convert readable dates into Unix seconds or milliseconds, then switch the output back into ISO 8601, SQL, or regional display formats. For dedicated epoch workflows, use Epoch Converter, Epoch to Date Converter, and Unix ms to Date.
Common Use Cases
- Converting between different programming language date formats
- Standardizing date formats for database import/export
- Converting API timestamps to human-readable formats
- Debugging date-related issues in applications
- Converting between regional date format conventions
Frequently Asked Questions
Q: How does auto-detection work? The converter analyzes the input pattern and matches it against known date format patterns to automatically identify the format.
Q: Are all conversions accurate? Yes, all conversions maintain precision and handle edge cases like leap years, daylight saving time, and timezone differences.
Q: Can I convert historical dates? Yes, the converter supports dates from 1970 onwards for Unix timestamps, and much earlier dates for other formats.
How do I convert JSON date to Unix timestamp? Paste an ISO 8601 or JSON-style date string, then select Unix timestamp as the target format. The converter can output seconds or milliseconds depending on the workflow you need.
How do I convert SQL datetime to epoch? Enter the SQL DATETIME value, let the format detector classify it, and choose Unix timestamp output to normalize it for APIs, ETL jobs, or event pipelines.
