Question

Below is the best way I have found. Thoughts? If you load this up and run is there a faster way to get it to load then what I have done here? Is there anything I am missing?

void Main()
{
    Console.WriteLine(GetMonthStart(DateTime.Now));
    Console.WriteLine(GetMonthEnd(DateTime.Now));
}
private DateTime GetMonthStart(DateTime dt)
{
    dt= dt.Date;
    return dt.Subtract(TimeSpan.FromDays(dt.Day - 1));
}
private DateTime GetMonthEnd(DateTime dt)
{
    dt= dt.Date;
    return GetMonthStart(dt).AddMonths(1).Subtract(TimeSpan.FromTicks(1));
}

Answer 1

Not sure if better, but I would probably do

private DateTime GetMonthStart(DateTime dt)
{
    return new DateTime(dt.Year, dt.Month, 1);
}

private DateTime GetMonthEnd(DateTime dt)
{
    return new DateTime(dt.Year, dt.Month, DateTime.DaysInMonth(dt.Year, dt.Month));
}
