CompChem Observer is free to use, has no ads and records nothing about your visit. Hosting it and running the automated checks of its sources still costs money.
If the calendar saves you time, a donation helps cover hosting and those checks, and keeps the site independent.
Other ways to help
- Add an event you know about, or correct one that is wrong.
- Suggest a source we should be checking.
- Improve the code behind the site
