DateDistance uses precise calendar mathematics to handle varying month lengths and leap years correctly. When adding months, we preserve the day of the month when possible (e.g., January 15 + 1 month = February 15), but adjust to the last day of the month when necessary (e.g., January 31 + 1 month = February 28/29 depending on leap year).
Business days are weekdays (Monday through Friday), excluding weekends (Saturday and Sunday). Our business day calculator counts only these weekdays. You can also choose to exclude holidays based on various regional calendars, which is particularly useful for contract deadlines, financial calculations, and project planning.
Yes, DateDistance is time zone aware. For date calculations without specific times, we use standardized calculations. For time-specific calculations, we detect your local time zone and show results in both your local time and UTC. This helps prevent confusion when working across different time zones.
Absolutely! DateDistance allows you to combine different time units in a single calculation. For example, you can calculate "2 years, 3 months, 1 week, and 5 days" from today, or any combination of years, months, weeks, days, hours, and minutes. This is especially useful for complex planning scenarios like project timelines, contract terms, or event planning.
