Execute Rule on specific data


I need a help in setting up a Rule to execute only on a specific date (18th ). I tried using {DATE:dd} Equals 18 but does not execute. However if i put {DATE:ddd} Equals Thu it works. Please help

What event, dd should work…

Try to change the condition to {DATE:dd} Matches 18

Thank you. Changed the condition to Matches from Equals and it works fine
