Thanks for the reply dognose. I did find that page which is why I thought it was Egyptian, before I found this site I had no idea so that helped. I also found a chart with the dates (

Hopefully someone can shed some light on the year and also what any of the other marks mean.
I have found a similar, but not identical, one on another site but it looks like that one has the cat symbol so it's older than mine.
