- duration-days ("$1 {{PLURAL:$1|day|days}}")

Are they being used:
- at the beginning of a sentence?
- inside a sentence?
- in a list?
That requires different initial capitalization.
Are the meant to denote:
- a duration? (… for 7 seconds …, … after a time of 7 seconds …, … once 7 seconds were over, …)
- a point of time in the future? (… in 7 seconds from …)
- a point of time in the past? (… 7 seconds ago …)
Any of those may require different wordings.
