@spogue Not sure if you can get them concurrently but you can use multiple plus_time calls to get the next three days and %A in the format to get the weekday.
{{ datetimeformat(local_dt|plus_time(1, ‘days’), “%A”) }}
{{ datetimeformat(local_dt|plus_time(2, ‘days’), “%A”) }}
{{ datetimeformat(local_dt|plus_time(3 , ‘days’), “%A”) }}
