I recently shared this list I compiled of Las Vegas event calendars with my mastermind group, and they shared it with their networks, which made me realize that it was time to share it. If you are planning an event and would like to submit your event to community event calendars, here are a few to get you started:
Las Vegas Review Journal (also submits to Las Vegas City Life)
Las Vegas Weekly
I wish you the best of luck in planning your event and hope that this list was able to help!
