Hello,
I just added my first Christmas tree to the map after reading your post (changeset).
Merry Christmas to the OSM Community!

An overpass query with all the things I support:
I have added the main cribs and Christmas markets that can be visited in Malaga. Also the three most unique lighting and light shows in the city.
They already appear on your map!

I just added this Three Wise Men mailbox to the map. I guess xmas:feature=santas-letterbox is the appropriate tagging in this case. The Three Wise Men are the equivalent of Santa Claus in Spain. They bring gifts for children on January 6.

Interesting in Spain the Three Wise Men bring the gifts 
Christmas is celebrated in very different ways around the world. In Bavaria, the Christ Child brings the presents. In Russia it is not a religious celebration and the name is New Year’s celebration
A small clarification: in Russia, too, some people celebrate Christmas, but it is celebrated on January 7th. And the new year is much more common and is celebrated on the night of December 31 to January 1.
Hello Dmitry, of course you know better what is the same or different between the festivals.
Now there’s more support for the xmas:feature=crib_museum, which is primarily registered as a museum (tourism=museum). And more new Functions 
crib_museum for example

I have added to the map a lot of Christmas objects this year, including trees, lighting, cribs, markets and even an ice rink (unusual in Malaga except at Christmas). Next year I will check them and maybe add some new ones.
Thank you for your map!

Thank you Christmas is a beautiful time. With this entry you help other people and yourself to have a good time I use the map every year and was very sad when the old map went offline.
Hi, I have now also added Wikimedia Commons key. I saw that you used this one many times.
Hello,
In the Corona Pandemic, one or the other Christmas objects were deleted from OSM because they did not take place in those years. Sometimes also unintentionally or unfortunately deleted on purpose. But a new object can also only have been created by editing.
With this link you can find the objects again:

Greetings Michael
Just in case you don’t know - you can use overpass to search for things that existed at a certain time in the past?
Yes, I used that to get the data for 2020-01-13 and 2020-12-19. Overpass took a long time to deliver the data so I’m loading it from a static json file. But thank you
Yes I take https://overpass-turbo.eu a dev server is tuned faster for old data that does not change anymore, a file is also ok.
Can I bring the object back with id-editor? Or only with JOSM Reverter?
