Short answer: No, we do not support embedding Event Pages or individual elements outside of Splash.
If you're looking to build an events calendar, we do support embedding Hub Pages. You can find out how in our Help Center article How do I embed my hub on another website?
We do offer ways to connect your Splash site to a domain you own (refer to Setting Up a Vanity URL), so that it provides an integrated branding experience for your guests.
If you're looking to embed Splash into an email or other interactive content, we recommend using an image (like a screenshot of the Share Card) and linking out to your site.
