Time zones are regions where the same standard time is used, divided by lines of longitude. The Earth is divided into 24 time zones, each corresponding to 15° of longitude, as the Earth rotates 360° in 24 hours. This means each time zone differs from its neighboring zone by one hour. Longitude directly influences time calculation, with locations east of the Prime Meridian having later times and those to the west having earlier times. For example, India’s time zone (IST) is 5.5 hours ahead of GMT due to its longitude.
