If you've got the option, you can turn on a live calendar so you can see your upcoming and past duties in the calendar on the device of your choice.
Go to My Details.
Select the Enable Live Calendar tickbox.
Click Update Details.
You'll get a unique URL for your duties calendar. Then you can add it to the device of your choice.
Please read the documentation for your specific device to see how to add the calendar:

📌Note: If you disable and re-enable the calendar, your unique URL for your account will change and you'll need to add it again. By default, your calendar updates once an hour. To change this, please look at the documentation for your chosen device, linked above.
