Calendar Considerations
When calculating dates, it's important to consider leap years, varying month lengths, and different calendar systems. The Gregorian calendar, used in most of the world, has specific rules for leap years that affect date calculations.
Business Day Calculations
Business day calculations exclude weekends (Saturday and Sunday) and may also exclude public holidays depending on the context. This is particularly important for financial transactions, legal deadlines, and business planning.
Time Zone Considerations
When working with dates across different time zones, it's important to consider the local time and potential differences in date boundaries. Our calculator uses your local time zone for consistency.
