Round Robin by date

[Egor Grijuc]

Hi.

I am wondering is there a way to keep data in table for exact period.
For example, keep calls data for period of 4 months and when some record reaces
his limit-perform a delete.
For example date now is 2014-02-07 12:00:00
A table have a record with date column and date is 2013-11;07 12:00 so it
needs to be deleted.

The only idea, that i have is a trigger or stored procedure that will be started
from cron and performing a delete where date <= DATE_SUB(NOW(), INTERVAL 4 monts); or something like that...

But i don't like cron jobs.
Is there another way to this without cronjobs but in automated mode?
Thanks
