Title an entity with a varying calculated day of the week

I have an entities card showing 7 entities for the upcoming 7 days which are named today, tomorrow, day 3, day 4, day 5, day 6 and day 7. I want to change the friendly name of the entity in the card to show the actual name of the day of the week in [3] days time (so say Wednesday for Day 3 and Thursday for Day 4) but struggling to get it to show. Any help really appreciated. Entity Card code below. I tried to add {{ (now() + timedelta(days=1)).strftime(‘%A’) }} as the name but it just shows that as the name.

  • entity: sensor.solcast_pv_forecast_forecast_today
