A very simple calendar to be displayed on your desktop similar to a Vista or Windows 7 gadget, but also works for Windows XP.

CalendarGadget

A simple compact calendar that displays discreetly on the desktop, similar to a Vista or Windows 7 gadget, but also works for Windows XP and Windows 10.

After logging in to your Google account (clicking on G on the right) you will be able to see your calendar entries. You will need to login only once as CalendarGadget remembers your login (safely stored in an encrypted token).

Right-clicking on a date brings up a context menu that allows you to perform some date calculations, such as adding 100 days to the clicked date or a formula for more complicated cases.

The desired date in each case is clearly displayed (in orange) on the calendar, and a tool tip also displays the performed calculation for verification.

You can use an arithmetic expression to calculate the date you want, for example, if you buy a new 100-pack of your vitamins, you can calculate how long it will last if you take 3 of them a day (100/3). If you plan to stop taking them for 3 weeks, you can figure out when you would start again (100/3 + 3w). And how long the second 100-pack will last (100/3 + 3w + 100/3). You may only use whole weeks, months, and years in these formulas (fractions of these are not useful, in my opinion).

Features

• remains almost hidden until you touch it with the mouse
• easy navigation using the arrows and the month drop down
• shows calendar weeks
• optionally shows Google calendar entries
• able to do date calculations based on formulas with days and full weeks, months, and years

Acknowledgments

• used tinyexpr from Lewis Van Winkle to evaluate date expressions like 100/2 +30

qt-calendar-gadget's Issues

Feature request: Add date calculations

I often have to do simple date calculations, such as adding 100 days to next week's Tuesday, to figure out when I need to reorder my vitamins. It would be handy if I could right-click on next week's Tuesday in the calendar view and had a field where I can enter +100 days, press OK and Calendar Gadget fast forwards and marks the respective day. It could also add the calculation to the pop-up of the respective day like this
