[GoT] How do calenders work in Westeros?

I'm not a Game of Thrones fan so sorry if this is obvious, but how do they make sense of years if their seasons are so irregular?

There are still other ways of keeping time. The passage of the moon, and the roatation of the stars in the sky. They keep a regular set of days and months and just make a special note of Summer or Winter based on the length of the days, temperature, snow fall, etc. It's not like in our world where some months are summer and some are winter, they can go literally years of one or the other. That isn't to say some months aren't warmer or colder than others, they just don't group them like we do.
