If you take a look in our Calendar section you might see that we now have the FR holidays listed under their real life equivalent dates. This is by no means a hard and fast date you must go with. For instance, if something like the Feast of the Moon falls in the middle of the week, this doesn't mean that you can't plan an event the weekend before or weekend after that date. The holidays shown are only to help a player keep track of when it should/could generally be.
The holidays listed only go two months in advance. As of the date of this post, only the holidays for October and November are listed. At the first of each month (though I hope to get to it a little bit before that

) I'll post the holidays for the next two months. As the dates will be rotating anyway, year to year, it's easier this way and I don't have to post 12 months worth of holidays all at once.
I'm currently using the following sites for reference:
