Nearest completed quarter

Question

Is there a C# function which will give me the last day of the most recently finished Quarter given a date?

For example,

var lastDayOfLastQuarter = SomeFunction(jan 3, 2010);

would set lastDayOfLastQuarter = Dec 31, 2009

Answer 1

You can use a simple switch statement to check which quarter the given date falls and return the last day of that quarter.
