I have been making bird photo calendars as Christmas gifts for friends since 2021. Several of those friends see my posting of bird photos on Facebook and often "Like" the photos, so I figure that they'd appreciate a calendar. One of my friends likes my calendars so much that he saves them every year, cuts out the photos and has made a "Bird book" for his little grandson. Another friend has said that she is starting to get a pile of them because at the end of every year, when she's going to put the calendars into the recycling bin, she feels so guilty about destroying such lovely photos that she keeps them.
I still use wall calendars, but I don't care if my friends do or don't. It is a gift, given in the spirit of the season, and what they decide to do with it is up to them.
I do all of my bird/nature photo cataloging using my Mac's "Photos" app. So saying, I create the calendars using the Motif/Mimeo app that is free on the Apple app store and integrates into the Photos app on the Mac. The calendars are large (13"x10") and made of nice, heavy card stock, but they're expensive (~$40 USD each). However, they do allow me to ship just about anywhere and have various shipping options & pricing.
I discovered a less expensive printer last year in a surprising place ... FedEx! They have an online printing service that allows you to make wall calendars, although the calendars are smaller (8.5"x11"), but they only cost ~$30 USD. Plus, as I recall, the shipping was two-day shipping to anywhere in the U.S. The only drawbacks were:
1) there are SO MANY calendar templates to choose from it is time-consuming finding the right template, and,
2) the boxes for each day were smaller than what I was used to and I often could not comfortably fit the name of some holidays in to the box.
(There are always trade-offs.)
Anyway, my opinion is, if making the calendar gives you joy, then make it. If a friend says that they'd rather not get them, then don't give one to that friend. And as I mentioned above, it is a gift, given in the spirit of the season, and what they decide to do with the calendar is up to them.
