Date & Time Utilities
Convert timestamps, format dates, and calculate time differences with precision. Essential tools for developers working with time zones, APIs, and data processing.
Date to Unix Timestamp
Convert human-readable dates into Unix timestamps (seconds since January 1, 1970 UTC). Essential for database storage, API interactions, and cross-platform date handling.
Examples:
Date Input Formats:
2024-03-15 → 1710460800March 15, 2024 → 171046080003/15/2024 → 17104608002024-03-15 14:30:00 → 1710512200March 15, 2024 2:30 PM → 171051220015-Mar-2024 14:30 → 1710512200Supported Input Formats:
- ISO 8601 (2024-03-15T14:30:00Z)
- RFC 2822 (Fri, 15 Mar 2024 14:30:00)
- US format (03/15/2024)
- European format (15/03/2024)
- Natural language (March 15, 2024)
- Time included (with hours, minutes, seconds)
Use Cases:
- Database timestamp storage
- API request parameters
- Log file processing
- Event scheduling systems
- Data export and import
- Cross-platform date sharing
Unix Timestamp to Date
Convert Unix timestamps back into human-readable date and time formats. Perfect for debugging, log analysis, and data interpretation.
Examples:

Calculate Date Difference
Calculate the difference between two dates in various units (days, hours, minutes, seconds). Essential for duration calculations, age computation, and time-based analytics.
Example Calculations:
Date Range:
To: March 15, 2024 3:30 PM
Time Difference:
Business Context:
Calculation Types:
- Exact duration (years, months, days)
- Total time in single units
- Business days calculation
- Working hours calculation
- Age calculation (precise)
- Time until/since specific date
Use Cases:
- Project duration calculations
- Age verification and computation
- SLA and deadline tracking
- Employee tenure calculations
- Event countdown timers
- Performance metrics and KPIs
Date & Time Best Practices
✅ Do
- Store dates in UTC in databases
- Use ISO 8601 format for data exchange
- Handle timezone conversions properly
- Validate date inputs before processing
- Use consistent date formats in APIs
- Consider daylight saving time changes
❌ Don't
- Assume local timezone for all users
- Use ambiguous date formats (MM/DD vs DD/MM)
- Ignore leap years in calculations
- Store dates as strings without timezone
- Hardcode timezone offsets
- Mix different timestamp formats
Common Timestamp Values Reference
Unix Epoch: 0 (Jan 1, 1970 00:00:00 UTC)
Y2K: 946684800 (Jan 1, 2000 00:00:00 UTC)
Leap Second: Consider 86401 seconds in some days
Max 32-bit: 2147483647 (Jan 19, 2038 03:14:07 UTC)
Millisecond precision: Multiply Unix by 1000
Microsecond precision: Multiply Unix by 1,000,000
Common formats: ISO 8601, RFC 2822, RFC 3339
JavaScript Date: Uses milliseconds since epoch
