Is date masculine or feminine?

Question

If we express dates as masculine (le 30 novembre), why do we ask Quelle est la date with feminine articles?

Accepted Answer

Don't confuse expressing the individual nouns that describe numerals and numeric date/days/months/seasons with speaking or asking specifically about 'the date'. 
« date » is a feminine noun so will always use « la » as definite article.  
Numerals (and the letters of the alphabet) are always masculine nouns using the definite « le ». (For later reference though the 'approximations' of number ending in « -aine eg une dizaine » are feminine nouns)
Days of the week and months of the year are also always masculine, as are the seasons.
« La date est le 30 Novembre »

Answer

Date is a feminine noun. so we use quelle (not quel).using quel or quelle for asking a question is based on a noun gender . for example age is masculine so we say : quel age avez vous?
