Well you're not specifying "the current date" anywhere - you haven't assigned a value to your dt variable, which is what the compiler's complaining about. You can use:

DateTime dt = DateTime.Today;

Note that that will use the system local time zone - and the date depends on the time zone. If you want the date of the current instant in UTC, for example, you'd want:

DateTime dt = DateTime.UtcNow.Date;

Think very carefully about what you mean by "today".

Also, a slightly simpler alternative version of your calculation would be:

int quarter = (month + 2) / 3;

This was a good start, I ended up using this line. Seemed more straightforward as to the goal, instead of adding 2.

Math.Ceiling(DateTime.Today.Month / 3m)

dt is currently assigned null. You need to initialize it with DateTime dt = DateTime.Now;

Technically speaking, `dt` is not assigned to anything – Andrei Jan 21 '14 at 19:05

In particular, it can't be `null` - `DateTime` isn't a nullable type. – Jon Skeet Jan 21 '14 at 19:06
So if it is not `null`, what is the value then? The pointer to null? Or just rubbish in memory at that time? – Christophe De Troyer May 16 '16 at 19:39
@ChristopheDeTroyer I found your question interesting. This answer seems correct and was in line with my thinking https://stackoverflow.com/a/2929297/540156 – onefootswill Mar 13 '18 at 03:19

It's initialised with the value of default(DateTime) which has the value of 1/1/0001 12:00:00 AM
