[whatwg] brief question on 2.4.5 Dates and times

[Silvia Pfeiffer]

Hi,

I am trying to use the specification of Dates and times given in section
2.4.5.

I was surprised to find that there is a specification of a valid month
string, but not of a valid year string or a valid day string. Is that an
oversight?

Regards,
Silvia.
