My Monthly Calendar displays events from a linked Google account in a monthly view with days of the week along the top, and weeks going down, similar to how it's laid out in google: https://calendar.google.com/calendar/r/month
When opened it will display your calendar, as much as Alexa allows at once. You can then ask it about various entries you have in your calendar, either via voice, or by tapping on an entry. You can also tap on a day and it will tell you what events you have then. You can subscribe for a dark theme.
