Euros in Denmark

Not really. If you find a shopkeeper that takes Euros, he's going to short you on the exchange rate. It's best to use a credit card anytime you can and pickup a few Krone out of a bank ATM for pocket cash.
Same goes for Denmark and Norway--very expensive places.

Thanks.

As a general rule foreign currency are usually not accepted in any country. If you find a merchant willing to accept it, it's going to be at an exchange rate they choose, usually a rip off.
Unlike what David is trying to tell you, Denmark is not more expensive than other major European cities like London or Paris. The trick is staying clear of the tourist traps.

Credit cards are widely accepted, but if you don't have one with a pin, be sure and tell the cashier that you want signature.

Denmark is expensive compared to most European countries, but similar to major cities like London and Paris.

Norway is even more expensive.

Is the Euro also accepted in Denmark?
Is the Canadian Loonie accepted in the USA?

Denmark is expensive compared to most European countries... Norway is even more expensive.
And the Norwegians are ranked first in the World Happiness Report and the Danes ranked second.

Norway has jumped from 4th place in 2016 to 1st place this year,
followed by Denmark, Iceland and Switzerland in a tightly packed
bunch. All of the top four countries rank highly on all the main
factors found to support happiness: caring, freedom, generosity,
honesty, health, income and good governance.

BTW Finland ranked 5th, Netherlands ranked 6th, and Canada ranked 7th. The US ranked 14th, the UK ranked 19th, France ranked 31st and Italy 48th.

no; you got the wrong area of the world. try this in Mexico

Some years ago, we did a house exchange in Copenhagen. We were there and in other parts of the country for several weeks doing tourist things, but also shopping in supermarkets, etc. We found that big operations, like supermarkets, did accept some foreign currencies including euros. The clerks had charts or calculators which gave them the price conversions and change due in krone. One would have to be really naive to think you get the best rate under those circumstances. I can't even remember why we did it, but I'm sure it had something to do with convenience. Anyway, the answer to your question is a qualified yes, in certain places; but better to use credit cards or get krone from an atm.
