About the date calculator
Two modes. Difference tells you how far apart two dates are in years, months and days, and also as a total in days, weeks, hours and minutes, with an option to count only working days. Add or subtract shifts a date by any mix of years, months, weeks and days and gives you the resulting date with its weekday and week number.
