Create a date time with month and day only no year

Question

I am creating a timer job in VS for sharepoint, and I want to create a Date object that only has a month and day. The reason for this is because I want this job to run annually on the specific date.

If it's not possible with a date object, then how would you go about doing this?

Here's what I've got:

DateTime value = new DateTime(2010, 1, 18);

How about creating a timer with the next date?

In your timer callback you create the timer for the following year? DateTime has always a year value. What you want to express is a recurring time specification. This is another type which you would need to create. DateTime is always represents a specific date and time but not a recurring date.

Well  you can create your own type - but a DateTime always has a full date and time  You can t even have  just a date  using DateTime - the closest you can come is to have a DateTime at midnight   You could always ignore the year though - or take the current year      Consider whether you want DateTime UtcNow Year instead DateTime value   new DateTime DateTime Now Year  month  day     To create your own type  you could always just embed a DateTime within a struct  and proxy on calls like AddDays etc   public struct MonthDay   IEquatable lt MonthDay gt        private readonly DateTime dateTime       public MonthDay int month  int day                dateTime   new DateTime 2000  month  day              public MonthDay AddDays int days                DateTime added   dateTime AddDays days           return new MonthDay added Month  added Day                 TODO  Implement interfaces  equality etc     Note that the year you choose affects the behaviour of the type - should Feb 29th be a valid month day value or not  It depends on the year     Personally I don t think I would create a type for this - instead I d have a method to return  the next time the program should be run

There is no such thing like a DateTime without a year   From what I gather your design is a bit strange   I would recommend storing a  start   DateTime including year for the FIRST occurence  and a value which designates how to calculate the next event    this could be for example a TimeSpan or some custom structure esp  since  every year  can mean that the event occurs on a specific date and would not automatically be the same as saysing that it occurs in  365 days   After the event occurs you calculate the next and store that etc

Anyway you need  Year     In some engineering fields  you have fixed day and month and year can be variable  But that day and month are important for beginning calculation without considering which year you are  Your user  for example  only should select a day and a month and providing year is up to you   You can create a custom combobox using this  Customizable ComboBox Drop-Down   1- In VS create a user control   2- See the code in the link above for impelemnting that control   3- Create another user control and place in it 31 button or label and above them place a label to show months   4- Place the control in step 3 in your custom combobox   5- Place the control in setp 4 in step 1   You now have a control with only days and months  You can use any year that you have in your database or
