About the startup
DateCalx provides a collection of free online date and time calculators designed to make everyday calendar calculations fast and accurate. Users can calculate the exact difference between dates, determine age on a specific date, add or subtract days, calculate business days, count down to future dates, and work with weeks, months, years, durations, leap years, and other time-related calculations. The calculators use real calendar rules rather than rough approximations, accounting for leap years, varying month lengths, weekends, and business-day rules where applicable. Business-day tools can also account for country-specific public holidays and customizable weekend schedules. DateCalx is designed for personal planning, work deadlines, contracts, payroll, invoicing, shipping timelines, education, travel, events, and everyday date questions. The platform is completely free, requires no account or signup, works on mobile and desktop devices, and provides instant results with clear breakdowns
