👉 Calendars computing involves managing and calculating dates, times, and recurring events across various time zones. It requires handling complex rules such as leap years, daylight saving time changes, and different calendar systems (like Gregorian, Julian, or Islamic). A key component is the use of algorithms to determine the start and end dates of events, account for time zone differences, and ensure consistency across multiple occurrences or intervals. For instance, a calendar might need to calculate the next holiday date based on a user's preference or automatically adjust event times for different regions. This process often involves sophisticated date arithmetic and sometimes machine learning to handle edge cases or user-specific preferences, ensuring accurate and reliable calendar management.
