Color contrast issues on website schedule

[erosselli]

Hello! I wanted to report an accessibility / color contrast issue with some of the text in the website, particularly in the "Our schedule" section of the website homepage. The dates show up in a light grey color that does not have sufficient color contrast with the white background (see attached image). Changing the text color to a darker grey or blue would fix the issue.

I'm happy to submit a PR to fix it myself, just wanted to call it out here first 😄
