Important dates in April

Hi everybody, just a few lines to remind you that on 23rd April it is S. George's Day. I know you are busy organising the activities for that special date in our school, but I would like you to look for information about this day in England. Also, on 25th there is an important celebration in Australia and New Zealand. Which celebration am I talking about? The next entry for the blog could be on any of these two dates.
