Regex Editor & Tester

Matches ISO 8601 datetime strings (e.g., 2024-01-15T14:30:45.123Z) using Python named groups for easy component access. Captures the date as YYYY-MM-DD ('date'), the time as HH:MM:SS with optional fractional seconds ('time'), and an optional timezone of Z or ±HH:MM ('tz'), plus the combined datetime in 'fulldate'. Ideal for parsing logs, API timestamps, and validating datetime formats in Python.
