[johnny603]

Is your feature request related to a problem? Please describe.
So I always feared that I would be late for my next event and would constantly need reminders and travel tips, including how long it would take to get to my event.

Describe the solution you'd like

1. Since the date is mm/dd/yyyy, the add button should stay consistent in that format
2. Give options on the date and time format including military time
3. language integration for the numbers
4. Email and Calendar integration, specifically starting with Google Calendar and Gmail
5. Google Maps so we can figure out the total time to get to an event
6. Reminder timer

Additional context
This feature set aims to create a comprehensive event management experience within the to-do list app, allowing users to stay organized, reduce anxiety about being late, and focus on their tasks without constantly worrying about their schedules. Users can manage their time and commitments by enhancing the app with these integrations and features more efficiently.
