How many business days between two dates?

Easy Date Converter allows you to answer such questions easily, and to perform arithmetical operations with Gregorian (a.k.a. Common Era) and Julian dates, dates in the ISO 8601 Week Calendar and in the Hermetic Leap Week Calendar, Julian day numbers and ordinal (day-in-year) dates of the form yyyy-ddd. It is a bilingual English/German program.

Suppose you run an advertisement which expires 45 days from today. What date will that be? How many weekdays are there in 2010? If you have an investment which matures on June 30th, 2011, how many days away is that? What date is the 203rd day of this year? If a loan is made on October 23rd, 2010, for 33 months, when will it be due? When will be (or was) the 10,000th day in your life? How many weekdays in a given year? How many years, months and days until December 21st, 2012? How many business days between two dates? If you find this sort of calculation a bit difficult then this program will make it easy.
