To open the Console press Shift+O then type the command and press Enter.
To get the console if you don't have it I recommend using UnRen because it's easy to use and it offers more options.

change the "x" with the number you want
money = x
day = x (by adding or removing days you change the days of the week, for example if you want to always have "Monday" and you have lets say 421 days and you are at "Night" set the day to 420 and do what ever you like to pass the night and in the morning you'll be at day 421 on Monday morning)

were x is :
1 for "Morning"
2 for "Afternoon"
