how can a get birthdays of month in date field dd/mm/yyy ?

Hi Zoho Team / Friends

In zoho crm, i've imported my contacts, where date are in dd/mm/yyyy format, used in Brazil. In the CRM, i'm trying to classify date field to get birthdays of the month (to send an email and attribute  a task to sales team) , but in this way, i can't get that information. It does exist a way to get birthdays of the month in crm, or i'll need to export to another app ?

Grateful
