Microsoft used to have macro-enabled templates that let you set the year or month and have the dates adjust. They have stopped offering those, perhaps because people were afraid of the macros.

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 2026 calendars. This is based on experience since they discontinued the macro-enabled calendar templates.
