ISO 8601 to Unix Timestamp Converter
Quick Answer: Paste an ISO 8601 date string (e.g., 2024-01-01T00:00:00Z or 2024-01-01T00:00:00+05:30) to get the Unix epoch timestamp in both seconds and milliseconds. Timezone offsets are handled correctly.

FAQ
What if my ISO date has a timezone offset?
The converter handles offsets like +05:30 or -08:00 correctly. The resulting Unix timestamp is always relative to UTC epoch.
What if there is no timezone in the string?
A date without timezone (2024-01-01T00:00:00) is ambiguous. It will be interpreted as UTC by this tool. Always include Z or an offset in production code.
