Need to schedule something across multiple timezones? Timezone Calendar gives you a side by side comparison of as many timezones as you like, helping you to select a time that will be perfect for everyone involved.

What’s New

Version 8.0

Full Chinese (Simplified) user interface localization.

Calendar view localization for nearly all iOS locales as well, meaning that local representations of times and dates are shown in the calendar view. As before, you can add timezone cities in many different foreign languages. Together these two features mean that while the app's user interface language may not be available in your language, once you add your timezones, you can still enjoy a fully localized experience.

Solid App

This needs an option to switch between 24 hour clock and AM/PM, and/or display both simultaneously. Other than that minor inconvenience is fail to find a flaw worth noting here. Good job developer, I purchased your iAP in the hopes that it aids you to add the above feature.
