If Sunday is coded as January, Tuesday as March, Thursday as May, then Saturday will be coded as:

Let's analyze the relationship between the days of the week and the calendar months:
* Sunday (1st day of the week in standard systems) $\to$ January (1st month of the year)
* Tuesday (3rd day of the week) $\to$ March (3rd month of the year)
* Thursday (5th day of the week) $\to$ May (5th month of the year)

The logic maps the $n^{\text{th}}$ day of the week directly to the $n^{\text{th}}$ month of the year using odd numbers ($1,3,5,\dots$).
Following this pattern:

* Friday would be the 6th day (if starting Sunday = 1), but let's count standard day steps:
* Sunday = 1st day $\to$ 1st Month = January
* Monday = 2nd day $\to$ 2nd Month = February
* Tuesday = 3rd day $\to$ 3rd Month = March
* Wednesday = 4th day $\to$ 4th Month = April
* Thursday = 5th day $\to$ 5th Month = May
* Friday = 6th day $\to$ 6th Month = June
* Saturday = 7th day $\to$ 7th Month = July

Therefore, Saturday corresponds to the 7th month, which is July.
