Hanging out with a guy on New Year's Eve... What does it mean?

I met this guy on a dating site. I've been out with him once- we met for coffee. He seems to like me and seems interested and I like him. We have been talking every day for hours pretty much. The day after we met for coffee, he texted me and invited me to a small gathering at one of his friend's houses for New Year's eve.

I'm not really sure what to expect or what he expects. I've never really spent New Years with a guy who wasn't my boyfriend. Do I consider this a date or is it a friends thing? Do you think he's expecting to kiss me at midnight? I'm just not sure what to do or what to expect and I'm kind of nervous. Does anyone have any advice? Thanks!
