It's just a set saying 'estar a' to refer to the date, the day or the temperature.
Hoy estamos a 15 de enero. Today is the 15th of January.
Estábamos al martes. It was Tuesday.
Estamos a cuarenta grados. It's 40 degrees.
On the 'Learn' lesson 1.14 around the 4:15 mark, there is a good explanation of this if you want to take a look.
