The world is divided into 24 standard time zones, each typically spanning 15 degrees of longitude. However, many countries have adopted time zones that don't follow these exact boundaries for practical, political, or economic reasons. Some large countries like Russia, the United States, and Australia span multiple time zones, while others like China and India use a single time zone despite their vast geographic size.
Coordinated Universal Time (UTC) serves as the primary time standard by which the world regulates clocks and time. Time zones are expressed as positive or negative offsets from UTC. For example, New York operates on UTC-5 during standard time and UTC-4 during daylight saving time, while Tokyo is always UTC+9.
Daylight Saving Time
Many countries observe Daylight Saving Time (DST), temporarily advancing clocks during warmer months to extend evening daylight. However, DST practices vary significantly: most of Europe and North America observe DST, while most of Asia, Africa, and South America do not. Some countries have recently abolished DST, and the rules can change, so it's important to verify current practices for accurate time conversion.
