HawaiiCalendar.com (formerly HawaiiCal.com) is the Hawaii Tech Events calendar, created to promote technology, science, startup, education, arts and fan events across Hawaii. From the Hawaii Geek Meet to Makerfaires to hackathons and more, all events that are open to the general public are welcome.

HawaiiCal.com is part of the Hawaii Hui. Founded in 1994 by Ryan Kawailani Ozawa, Hawaii Hui LLC (formerly Leahi.Net) is the largest and longest-running blog network and online publishing group in the Aloha State.


HawaiiCal.com was launched in November 2019 and was inspired in part by XLR8HI and its XLR8HI Startup Events Calendar, which is no longer being maintained.
