fetching sharepoint list items using caml query

Question

I created a list of birthdays with column Datetime that stores birthdays of employee (e.g. 20/10/1994). I want to get the date and month from the column of a custom list.

I want to run a timer job whenever current date is equal to the date of the column.

For that I need a caml query that fetch particular list item based on current date and month.
