You can choose from a variety of themes, customize the look of each page, add captions, national holidays, pull events from your Calendar app, and plop pictures onto individual date squares (great for birthdays!). The calendars you create in Photos can be customized in myriad ways. They’re stunning and they make great gifts. At 13 by 10.4 inches, Apple’s calendars are big and printed on thick, high-quality paper so they look better than the ones you get anywhere else.
A safe way to print-and thus enjoy-your digital memories is to create a calendar in Photos for OS X. There’s nothing like printing your own photography, though adorning your walls with your own art can be intimidating.
