Bank Holidays Precise Calendar

Hello!

I'm looking for a place where I can compare all dates where there are special events like Christmas, bank holidays, bank breaks etc...

I need to see all major exchanges at the world if they operate or not

I need something like this: https://prnt.sc/j186qh

... but of course I need to see all possible dates in such way.
Do you know any place that can support me with such informations?

Do they have google where you live?

Can you read thoroughly? I need a summary where I can see all exchanges and indices from all over the world and fx should be opened at that day. Actually I need exactly the same environment as Good Monday has, look here https://prnt.sc/j186qh
