Question about Glezer firm sourdough starter

Toast

My question concerns the feeding schedule.  Week one starts on Sunday, as calendar weeks usually do.  Week 2 starts with a Saturday refresh.  Is this Saturday two days later, which is technically still week 1, or am I to wait until day 9, which is actually the first Saturday in week 2?  Thanks!

Two days later after the first Thursday. Technically not worded right but you wouldn't wait 9 days between feeds.
