Google brought the At a Glance widget to its Pixel phones a few years ago, running it on devices with Android 7.0 or higher.
Since then, the iconic widget has been a fairly consistent feature of Google’s Pixel Launcher (i.e. the Home Screen setup in Pixel smartphones). It always shows the day and date in an easily visible space, and keeps you abreast of upcoming events or appointments, which it draws from the Google Calendar App.
