So who wants to fire up Google, Outlook, or other gigantic program just for a quick look at a calendar?
No one. Here is a simple calendar, a 6 month view, too simple really, but useful.

A bit more useful since one can also find the # of days from a start day to an end day, inclusive.
Also it can be used to show the resulting date once given a start date and +/- a number of days.
Lastly, it can also set a simple alert for a date & time. This is a one shot alert, no repeat function.

Version 2.0.2 supports four 'Methods' to schedule an alert; VBS, PowerShell 5.1, C, and PowerShell 7. The 'Method' to use can be selected, but defaults to C if no selection is made. An ini file has been added to store the 'Method' chosen.

It can be run from a USB, just three files, nothing written to the registry, no phone home or telemetry. Simple calendar with a few 'extras' thrown in...

Simple, free, small footprint, but hopefully useful.
