Calendar Systems
Calendar systems are frameworks for organizing and tracking time, typically based on astronomical cycles like the Earth's rotation (days) and orbit around the Sun (years). They include components such as months, weeks, and leap years, and are used globally for scheduling, historical dating, and cultural or religious observances. In computing, calendar systems are implemented in software for date-time handling, event management, and internationalization.
Developers should learn about calendar systems when building applications that involve date-time calculations, scheduling, or localization, such as calendar apps, booking systems, or financial software. Understanding different calendar systems (e.g., Gregorian, Islamic, Hebrew) is crucial for handling international dates correctly, avoiding bugs in leap year logic, and ensuring compliance with regional standards in global software.
