"Timeblocks" does this perfectly. Imo it's the most intuitive Calendar I found. If you paid for the $3 iap you'll be able to add Todos/tasks to the calendar as well.
center screen: on top agenda widget from TimeBlocks, weather from Today Weather and the last one is KWGT;
screen on the left: calendar view from TimeBlocks and calorie counter from MyFitnessPal ;
Screen on the right: widget on top from Year progress, to do list from Taskito, habit log from HabitNow, icons are also a widget to use Alexa commands
My favorites are TimeBlocks and Taskito;
Tiimo It's an interesting project, but for now a bit poor in functionality;
TickTick it's an evergreen, I personally stopped using it for TimeBlocks, but it is very valid
June might fit the bill: https://play.google.com/store/apps/details?id=com.hellowo.day2life
Maybe TimeBlocks?
I REALLY like this calendar app. It's half calendar, half to-do-list. TimeBlocks
