I use a lot of activities every semester whose dates have to be reset. It's a huge pain (literally) from all the clicking required, so I created a user script that works in Chrome (with the Tampermonkey plug-in). I thought it could be useful here.
Here's a screenshot of how it looks:
The reasons I find this way better to enter dates:
- I don't have to click (I can type the date and time entirely in the box);
- I can copy/paste dates in the text box.
- There's a "now" button which makes things go easier when I update from a course one year ago.
