📖 Understanding World Time Zones

Time zones are regions of Earth that observe the same standard time. The world is divided into 24 time zones, each approximately 15 degrees of longitude wide. The prime meridian at Greenwich, London (UTC+0) serves as the reference point.

India follows a single time zone - Indian Standard Time (IST) which is UTC+5:30. Unlike many countries, India does not observe Daylight Saving Time. This means the time difference between India and other countries can change seasonally for those that do follow DST.

For international business, travel, and communicating with friends abroad, knowing the correct time difference is essential. Our world clock shows real-time current time in major cities, helping you schedule meetings across time zones without confusion.

Pro tip: When scheduling international calls, use "UTC time" as reference and let each person convert to their local time. Tools like this world clock eliminate the guesswork from time zone conversions.
