Outlook on my office Exchange system for work.
Google Calendar for personal. My wife also uses Google Calendar so we can see each other’s events.
I can see the whole lot of it integrated on my Android calendar.
My old Android phone’s Clock app tells me when to awaken, take pills, etc. My wife handles the rest, mostly medical appointments and planned scurryings. We should scurry to Mendocino in a week; I remember that much. Then we’ll scurry back. We missed a T-day scurry but might make it for Xmas since we can’t make a San Diego scurry.
How does my wife track all this? In a paper datebook. It’s more reliable than electro devices here in PG&E land.
I use an ancient codex called an annual diary. They were very common in the 20th century, where I’m from. I just flip to the right date and jot stuff down. If the stuff isn’t going to occur until the following year, I just add it in the Notes section in the back. Towards the end of the year, after I buy a new diary for the next year, I’ll review this year’s Notes and add them to the new diary. I actually find it fun to pick out a new diary each year. If I’m out somewhere and don’t have my diary handy, I’ll note something down in my phone or on a random piece of paper and transfer it to my diary when I get home.
For bills that I know will always be the same amount each month (eg rent), I transfer the funds to a separate account as soon as I get paid. From there, they are set to auto-pay when they are due. For bills that vary (eg electricity), I pay the bill when I get it or when I next do my banking on pay day.
The manager of my apartment building takes the dumpsters out so I never need remember that, just to take the trash down to the basement once in a while.
My only recurring thing is taking the dogs out in the Jeep. They let me know.
Google Calendar runs my life.

Certain house maintenance tasks I write down in a A5 bound booklet. These are tasks that i want to know when did I do them last, to see if it’s time to do them again. Changing the Brita filter, washing the pillows, washing the duvet, etc. If I take a bit longer to do the task, I don’t get daily reminders about the task.
Normal appointments, such as doctor, dinner with friends, etc., go on the calendar. Apple products. Because “Siri” finds things in the email, there are sometimes multiple instances of flights, hotel bookings, etc., because we don’t check to see if it’s on the calendar before adding it. Oops.
Things that are a bit more time critical, such as picking up refills, remembering to put a load of laundry, go in the Reminders app.
And I use the Notes app to make todo lists for the weekend / vacation / other.
Most bills are paid automatically or I get an email or even a paper bill. Taxes go on the calendar, as these are done every 4 months (U.S.) or once a year (Switzerland). I already approved all the insurance payments which are due on January 1st. Of course they will get paid a couple days before the end of the year.
I use Google Calendar, with various reminders to warn me in advance about upcoming events that need advance prep.
For more temporary things I email myself in Gmail and Snooze the message.
I just use a calendar app on my smartphone. It helps me keep track of stuff like whether the recyclables or the yard waste is being picked up this week.
