What Is World Clock

World Clock helps you view current date and time across multiple cities in real time, with automatic daylight saving handling based on browser timezone rules.

Key Features

• Live city clock updates with date, weekday, and timezone offset.
• 12/24-hour display switch and seconds visibility toggle.
• Fast filtering by city name or timezone.
• Custom city management with local persistence after refresh.

Best Practices

• Check daylight saving differences before scheduling cross-timezone meetings.
• Keep your frequent collaboration cities in the saved list.
• If browser storage is blocked, city settings cannot be persisted.

Privacy Notice

No. Time calculations and city-list management run locally in your browser by default.
