How to know which contest is rated?

Hi community,
I just want to know how can we know about the rated contest on Codechef other than the Long Challenge, Cook-Off and the LunchTime.

Any help is appreciated.

As far as i know, these are the only 3 rated contests that take place consistently.
other than these i have seen a few take place which were rated only for div3, you will have to find out about these yourself.
its a good idea to come and check the future contest area to know what contests are coming up. If ay of these are rated, it will be shown on the contest name.
