A family of Microsoft word processing software products for creating web, email, and print documents.
Here is some more information and background.
Microsoft used to have macro-enabled templates that let you set the year or month and have the dates adjust. The information for templates still refers to the Calendar tab. It has vanished, though. They have stopped offering those, perhaps because people were afraid of the macros.
Per Bob Jones a while back , apparently, in the Mac interface, the template named "Calendar" also still contains the macros and the Calendar tab as in the description. @Bob Jones AKA CyberTaz MVP
If you have used a macro-enabled template from Microsoft in the past for this, it should still be on your computer in the folder you have designated as the default location for saving custom office templates.
When you use one of the templates from Microsoft, it is stored there.
I expect that sometime in January Microsoft will come out with 2027 calendars. This is based on experience since they discontinued the macro-enabled calendar templates.
There are good free alternatives available.
You can use the free calendar add-in from former Word MVP Greg Maxey that you can download from here: https://gregmaxey.com/wonrd_tip_pages/calendar_maker_addin.html This has several choices of formats.
You can also find free 2026 calendars on MVP Jay Freedman's download site. (https://jay-freedman.info/) These are simple macro-free templates.
You can find a free perpetual calendar maker add-in on MVP Graham Mayor's site. This allows a choice of background colors.
