I’ve got a second vote for Moongiant! I found the site recently and it’s been great- the front page has a countdown to the next full moon (makes it very exciting!) and on the calendar page you can click on any date for more information- they have a lot of information for each day, and even about each full moon! 
@Missa shared another great resource- the Farmer’s Almanac:
Although it seems that this moon calculator is just for locations in the U.S/Canada!
Best of luck and Blessed Be!
