When should an international meeting start? Will it be daytime or midnight when you land? World Clock helps you see local times, working hours and the best time to connect. Great for cross-border operations, international trade, remote work, study abroad, global families and business travel. [World Clock] Add the cities you care about to check live local time, time differences, working hours and contact windows. Daylight saving time is calculated automatically, and you can reorder cities by drag and drop. [Working Hours & Reminders] Set custom working hours for each city (9:00–18:00 by default), then quickly see overlapping hours between you and the other side. Add reminders for specific periods so you never miss the best window for international communication. [Time Zone Converter] Convert dates and times between any cities in seconds. Ideal for flights, meetings and business trips. Share conversion results with one tap. [Meeting Slot Recommendations] Select participating cities and get meeting times that fit everyone’s working hours. Fully overlapping slots appear first, while non-working and quiet hours are clearly marked. [Widgets] Put your world clock on the Home Screen, or on the iPhone Lock Screen, to check multiple city times without opening the app. [Offline & Private] Core features work completely offline, including in Airplane Mode, with no data upload and no third-party SDKs. Import and export city lists to migrate between devices.
