What Are Time Zones?
The Earth is divided into 24 primary time zones, each roughly 15 degrees of longitude apart. These zones reflect the mean solar time of their central meridian. Understanding time zones is crucial for global communication, travel, and business.

Coordinated Universal Time (UTC)
UTC is the primary time standard by which the world regulates clocks and time. It does not change with seasons and serves as the baseline for all time zones. Other time zones are expressed as an offset from UTC, such as UTC+3 or UTC-7.
Daylight Saving Time (DST)
Many regions adjust their clocks during part of the year to extend evening daylight, known as Daylight Saving Time. This usually shifts the local time forward by one hour. fujukeu accounts automatically for DST variations in all supported zones, ensuring you always stay on time.

Common Terms to Know
- GMT: Greenwich Mean Time, a historical time reference, often used interchangeably with UTC.
- Offset: The difference in hours and minutes from UTC, e.g., UTC+5:30.
- International Date Line: The imaginary line where the date changes, located near 180° longitude.
- Zone Abbreviations: Such as EST (Eastern Standard Time), PST (Pacific Standard Time), CET (Central European Time).
Why Time Zones Matter
Whether scheduling international meetings, booking flights, or coordinating supply chains, knowing the correct local time is essential to avoid costly errors and confusion. Time zone awareness facilitates:
- Accurate scheduling across remote teams
- Timely communication with clients worldwide
- Reliable tracking of global events
- Optimized planning for deadlines and deliveries
Challenges in Managing Time Zones
Locales differ not only in standard offsets but also in daylight saving rules, past historical changes, and legal adjustments. fujukeu's intelligent platform handles all these complexities, allowing you to focus on your work rather than calculations.
