I also love using Google Calendar! It is easy to set up meetings with other colleagues and add it to their calendar. They option to have a video meeting is also nice.
Yes, I agree it helps out a lot when you are able to plan meetings and such with colleagues and share invites. The google meet is good as you can do video chats as well. They have so many good features on Google to be able to share with colleagues and students.
I really need to use Google Calendar more this year. I never thought about putting specials in and always thought of it as when I have a meeting. This will be helpful the first week or so of school when I am still trying to learn my new schedule.
