I am having trouble deciding on how to set this schedule:

11:00–11:30
11:30–12:00
12:00–01:00

here I don't like the extra zero in front of the 1, but it makes everything nicely aligned with the dash and the colon.

Also I Think the numbers are redundant so I made this one but kept the 1:00 to show when the event ends:

11:00
11:30
12:00–1:00

Exept with a right alignment (html paragraph align is not working)

or

11:00
11:30
12:00

which I think is ideal, but I have a feeling the client will want the redundant numbers to show when the event is over.

Thanks.
