I searched on the internet for a quick way to get the Quarter from a DateTime, but I didn’t really find anything useful, so I created this quick extension that seems to work great! I just wanted to share this to save someone time so they don’t waste the same amount of time that I did. I am thinking about putting together an open source library to handle many other things like this, what are your thoughts about this?

public static class DateTimeExtensions { public static int ToQuarter(this DateTime dt) { int qtr = -1; if (dt.Month >= 1 && dt.Month <= 3) qtr = 1; else if (dt.Month >= 4 && dt.Month <= 6) qtr = 2; else if (dt.Month >= 7 && dt.Month <= 9) qtr = 3; else if (dt.Month >= 10 && dt.Month <= 12) qtr = 4; return qtr; } }
