We're currently in 2024 and I have been using Google Calendar since 2012, when I was in, High School to track classes, tests, and personal appointments. That's at least 12 years of calendar management experience. Since Google integrated Tasks into Calendar, I also feel like the experience improved, and I've been also using them quite a bit.

In my day job, I work remotely with clients all over the world, so you can imagine the number of meetings I have in a single week (honestly, I wish we reduced the number of meetings). There, we use Microsoft instead of Google nowadays.
