About DateKit
DateKit brings common date tasks into one consistent place. It is designed for people who need a clear result without counting calendar days manually, building spreadsheet formulas, or creating an account.
The site includes focused calculators for age, date differences, business days, date adjustments, event countdowns, and birthdays. Each tool explains the rules it uses and presents the result in several practical formats.
DateKit is available in English and Spanish, with localized routes, labels, explanations, and examples rather than a single interface with partially translated text.
The current version performs calculations directly in your browser. Dates entered into a calculator are not intentionally sent to a DateKit account, saved in a DateKit database, or used to build a personal profile.
Calendar logic is implemented explicitly for cases such as leap years, inclusive ranges, configurable weekends, excluded dates, and months without a matching day number.
DateKit is a general-purpose utility. It is not an official calendar, legal deadline service, payroll system, medical calculator, or substitute for professional advice.
For contracts, court dates, immigration processes, tax filings, employment deadlines, or other important matters, confirm the result with the responsible authority or a qualified professional.
