Sobre o Date Difference Calculator
Project deadlines, contract periods, pregnancy weeks, holiday countdowns — everything starts with "how long between these two dates?". Enter a start and end date to get the exact duration broken into years, months and days, plus totals in weeks and days, a business-day count that excludes weekends, and a plain summary sentence you can quote directly. Leap years and month lengths are handled precisely, not estimated.
