How does ToS aggregate Week & Month time periods?

Forgive the silly question, but when one sets a custom quote to "WEEK," is ToS aggregating the week-to-date, the past 4 trading days + the current day, or something else? And of course each MONTH comprises a different number of trading days and will open at a different point in a given week. Is a month aggregated based on days, weeks, 1/12 of a year, month-to-date, or something else?
