It's October

While we're at it [an English way to say, przy okazji], the same principle we wrote about in the last blog entry applies to time expressions like days, months, or years.  We don't say,

We have October

but 

It's October.

It's Monday.

It's 2013.

It's autumn.

And remember--the same applies when we're talking about our age, height, or weight:

I'm thirty-eight (years old), NOT I have thirty-eight (years)

I'm 194 cm [tall].   I'm 88 kilos  OR  I weigh 88 kilos.
