Can you sync events with another site’s Calendar

Hi, I have a client with 2 websites. Site A is their main site and Site B is their newer, more specialized website that I built them 2 years ago and haven’t touched since. Site B uses the Events Manager plugin, and I don’t know about Site A, since I was never involved with that, though I’m trying to find out the details.

Basically, they want me to make it so the events posted on Site A are automatically posted on Site B’s event calendar also. Is this possible with Events Manager? Any advice would be much appreciated.
