Rosetta Code: Date format - vague instructions

I wasn’t sure if I should combine this with the other issue with this challenge, but it seems separate.

The instructions give no clue of how to handle single digit months or days. The example has double digits for both:

Example output: ['2007-11-23', 'Friday, November 23, 2007']

So, a camper just complained because:

[ '2021-03-01', 'Monday, March 1, 2021' ]

wouldn’t pass. It will only pass with:

[ '2021-3-1', 'Monday, March 1, 2021' ]

I just thought I’d check and see if this was purposely vague - it seems like such an obvious omission.
