Add comparison cities relevant to your schedule: Click “+ Add City” and search for cities such as New York, London, and Dubai if you work with finance, shipping, or energy partners. These comparisons are practical for Port Arthur because Southeast Texas is tied to petrochemical, port, and freight activity, and many users need to align Gulf Coast work hours with East Coast offices, European trading desks, or Middle East energy contacts.
Drag across the grid to compare working hours visually: Click “Select” to enter selection mode, then drag on Port Arthur’s row from 9:00 AM to 11:00 AM to highlight a meeting window in purple. On a standard time comparison, that same slot is 10:00 AM to 12:00 PM in New York, 3:00 PM to 5:00 PM in London during U.S. standard time, and 11:00 PM to 1:00 AM in Tokyo, which quickly shows whether a Gulf Coast morning call is realistic for international participants.
Export or share the selected time range: After selecting a time block, use the export options shown on the page: ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially helpful if you are sending a plant maintenance call, shipping coordination window, or cross-border operations meeting so every participant sees the event in their own local time automatically.
