Here's some code which reproduces the problem (I'm in the Pacific time zone): DateTime dtStartLocal = DateTime.Parse("2009-02-28T23:00:00.0-08:00"); DateTime dtEndLocal = dtStartLocal.AddYears(3); DateTime dtStartUtc = dtStartLocal.ToUniversa...
I am writing a program that shows the current years sales from the beginning of the fiscal year to the current date, compared to the same date range of the year before.

Hello I am following "The Art and Science of Java" book and it shows how to calculate a leap year. The book uses ACM Java Task Force's library. Here is the code the books uses: import acm.program.*; public class LeapYear extends ConsoleProgram { public void run() { println("This program calculates leap year."); ...
Given two dates, what is the best method to calculate the number of days between those two dates that fall in a leap year. For example if d1 = 12/1/2007 and d2 = 1/31/2008 then the total number of days between d1 and d2 would be 62 and the number of days that fall in a leap year would be 31. Another example is if d1 = 12/1/2007 and...

Hi, I'm trying to sort out a result set that gives the 5 closest users sorted by upcoming birthday. This works perfectly until leap years comes into play. For example: May 15th - 96 days left May 15th - 97 days left The top result is a birth at 1987 and the lower is from 1988. u_birth is stored as yyyy-mm-dd. Is there a simple way to...
