Adding one day to last day of the month

DateTime dt = DateTime.UtcNow;  

var lastDayOfMonth = DateTime.DaysInMonth(DateTime.Now.Year, DateTime.Now.Month);
day = dt.Day;
if (day != lastDayOfMonth)
{
    if (dt.Hour >= 14)
    {
        day = day + 1;
    }
    else if (dt.DayOfWeek == DayOfWeek.Sunday)
        day = day + 1;
}
else
{
    //  
}

Now I want to add one day to the last day of the month. How can i do it?

Finally i did this by removing the if condition for lastDayOfMonth and using AddDays property.

                if (dt.Hour >= 14)
                {
                    dt.AddDays(1);
                }
                else if (dt.DayOfWeek == DayOfWeek.Sunday)
                {
                    dt.AddDays(1);
                }
                day = dt.Day;

thankyou everyone for your valuable suggestions.

Sounds like you just need DateTime.AddDays method

Returns a new DateTime that adds the specified number of days to the value of this instance.

But DateTime.Day property returns int. If you just want to add it 1, you are in a right way.

day = day + 1;

But this doesn't affect dt of course.

Ok, let's look at your exact problem now..

Adding 1 month and then extracting 1 day is the one of the best way to find out the last day of the current month.

For example;

DateTime dt = DateTime.UtcNow;
var FirstDayOfNextMonth = new DateTime(dt.Year, dt.Month, 1).AddMonths(1);
var LastDayOfCurrentMonth = FirstDayOfNextMonth.AddDays(-1);
Console.WriteLine(LastDayOfCurrentMonth);

Output will be;

2/28/2014 12:00:00 AM

Here a demonstration.

To find the first day of next month you can use

Datetime FirstDayofNxtMnth =DATE(YEAR(TODAY()),MONTH(TODAY())+1,1);

To find the Last day of this month you can use

Datetime FirstDayofNxtMnth =DATE(YEAR(TODAY()),MONTH(TODAY())+1,1);

Datetime LastDayofThisMnth =DATE(YEAR(TODAY()),MONTH(TODAY())+1,1).addDay(-1);

DateTime today = DateTime.Today;
DateTime firstDayOfThisMonth = new DateTime(today.Year, today.Month, 1);
DateTime firstDayOfNextMonth = firstDayOfThisMonth.AddMonths(1);
