Array Output of Dates

Hi,

I have a pod with a repeatable date field. The field is called “termine”. It outputs the array being shown like this “Date 1, Date 2, Date 3 and Date 4”.

Is there a simple way in the template to output the first date, the last date and the number of dates in this array, as in “Date 1 to Date 4 (4 Dates)” ?

Thanks,
Astrid
