Calendar

ui.Calendar creates a month's calendar choosing the day of a *time.Time, as SwiftUI's graphical date picker: a click chooses a day, as the arrows do while the calendar has the keyboard focus; Page Up and Page Down, or its buttons, move by months, and Home and End go to the first and the last day of the month. Changed reports a new date, which keeps the time of day and the location of the value.

ui.Calendar(c, &app.day).Label("Due date")

It shows six weeks from Monday, the days of the months around in gray, and marks today.

For a date in a compact field, use a date input, which opens this calendar below it.

Accessibility

Assistive technology sees a table named by its month, whose days are buttons named by their dates, and reads the day chosen as the arrows move.
