Saw my boss manually entering each date and weekday like this

The video shows a screen recording of Microsoft Excel. It starts with a user manually entering dates and weekdays. The video then demonstrates a shortcut to automatically fill in dates and weekdays. The user enters a starting date, presses ALT+E+I+S, configures the series to fill columns with dates and weekdays, and then uses a TEXT function to display the weekdays. The final result shows a long list of dates and their corresponding weekdays automatically generated. The pacing is quick and instructional.
