## About

## What it does
Date Time Converter turns a single timestamp into the formats developers actually use. Send an ISO 8601 value, a unix epoch, or `now`, optionally include an IANA timezone, and get back normalized UTC time, human-readable output, relative time, and localized details.

The response includes the original input, `iso_utc`, `weekday`, `iso_week`, `relative`, `human_utc`, `day_of_year`, `epoch_millis`, and `epoch_seconds`. When you pass `tz`, the `localized` object returns the timezone name, localized ISO string, localized human-readable string, and UTC offset. That makes it useful for log viewers, scheduling interfaces, analytics dashboards, and any system that needs to present the same moment in both machine-friendly and user-friendly forms.

Use Date Time Converter when you need to parse incoming event times, display timestamps in a user's timezone, or compare stored values across systems that disagree on time format. It is a straightforward way to convert one date-time value into multiple representations without rebuilding the logic in your application.
