THE most wonderful time of the year is just days away meaning major UK supermarkets will be altering opening times to give staff a well-earned break over the festive season.

It seems we spend the whole year planning for the big day only to realise we have forgotten something and make a mad dash to the shops.

It’s worth bearing in mind, supermarkets including Asda, Aldi and Tesco will be changing their opening times.

We've broken down all the major supermarket opening times during the Christmas period so that you don't get caught out.
