ISO Date Converter

Workflow & Usage

1. Paste or type an ISO 8601 date string into the input field.
2. The tool automatically parses the value.
3. View the converted results instantly:
   • Local date & time
   • UTC date & time
   • Unix timestamp (seconds)
   • Unix timestamp (milliseconds)
4. Use the Copy button on any output to copy it with one click.

Invalid inputs are safely ignored and won’t affect the rest of the interface.

Supported Conversions

ISO → Local Time

Convert an ISO date into your device’s local timezone.

Example:

2025-03-08T14:32:00Z → 2025-03-08 16:32:00

ISO → UTC

Convert an ISO date into a normalized UTC representation.

Example:

2025-03-08T14:32:00+02:00 → 2025-03-08 12:32:00 UTC

ISO → Unix Timestamp

Convert an ISO date into a Unix timestamp.

Examples:

2025-03-08T14:32:00Z → 1741444320 (seconds)
2025-03-08T14:32:00Z → 1741444320000 (milliseconds)

All conversions are performed instantly as you type.

Common Use Cases

• Inspecting API responses
• Debugging backend logs
• Verifying database timestamps
• Working with ISO dates in JSON payloads
• Converting ISO strings to Unix time
• Comparing timestamps across systems

---

Tips & Best Practices

• Use UTC output when working with APIs and distributed systems.
• Use local time to verify user-facing dates.
• Always check timezone offsets (Z, +02:00, etc.) in ISO strings.
• Prefer ISO 8601 for data interchange and storage.

How It Works

• ISO strings are parsed using the browser’s built-in Date engine
• Timezone offsets are respected automatically
• Unix timestamps are derived from the parsed date
• Each conversion is computed independently
• All logic runs locally, in real time
