You can use the CEILING function for this:

To explain:

=NOW() gives time at point of calculation

Adding 115/24 will add sufficient days and hours.

=CEILING(###,n) will round up the ### to the next factor of n. As dates are held as a serial number incremented from 01/01/1900 which happened to be a Sunday. The whole number being the date and the decimal portion of a number being the time eg 3am being 0.25 and midday being 0.5 etc

Therefore counting up in units of 7 will give the whole serial number dates for Saturdays. Then adding 5/24 to the result will be the decimal part of the number for 5am.
