Every other Saturday date

Hello,
Can you please help,
I have a stored procedure that fires some emails to my clients.
Currently it runs twice a month.
if DATEPART(day,getdate()) in (6,21)  
Begin xxxxxxxxxxx

I need to change the date to make it run every other Saturday. (Starting  January 6th, 2018)
Jan 6th, Jan 20th, Feb 3rd, and so on.

Any help is greatly appreciated.
