.Net DateTime fiscal Quarter

Question

Does anyone know how to construct a DateTime in .NET to be the first day of the current quarter?

Answer 1

public DateTime GetCurrentQuarter(DateTime date)
{
    int startingMonthOfQuarter = (((date.Month - 1) / 3) * 3) + 1;

    return new DateTime(date.Year, startingMonthOfQuarter, 1);
}

Answer 2

        var currentTime = DateTime.Now;
        var year = currentTime.Year;
        DateTime[] quarterStarts = {new DateTime(year, 1, 1), new DateTime(year, 4, 1), new DateTime(year, 7, 1), new DateTime(year, 10, 1)};
        var currentStart = quarterStarts.Where(s => s < currentTime).Last();
