Date Subtract every year

for every year on these dates i have to send email, but how can i write the logic to check that send email

in the table i have date column for that i have to check this date and send email 

the requirement is - Email notificaiton to be scheduled to send where the  Callback comments are not given in every quarter(last 3 months). and System to check if callback comments are present in the last 3 months and make the list of those data and send email 

to check callback comments are given or not from last 3 months we can use column updated on - on each time we write comment updating the date in updated on column
