How do you remember when your car MOT is due?

Having realised by chance yesterday that the MOT on DH's car ran out 2 weeks ago, it occurred to us that you get a reminder for car tax and insurance but not for MOT testing, which is also a legal requirement.
We have 3 cars and have never forgotten before - we are obviously getting old and forgetful - It is not something I've ever written on the calendar but somehow just we just seem to have always remembered in the past.

Obviously some of you are lucky enough to own cars that don't need an MOT but if yours does, how do you make sure that you remember to do it in time?

I am normally extremely organised and will in future be writing the dates on my calendar - unless any of you can offer a better solution.
I was also wondering how many cars on the road have no valid MOT because of similar forgetfullness rather than deliberate intent.

I’ve got an app called My Garage which sends notifications on my phone for everything.

I get a text from mot company and also a notification on the aa app. I usually remember though.

It's on hallowe'en - the scariest day of the year!

I just write it in my diary. Simple really.
