How do you count the days in your diary?

I count the first day when it pops out of the soil. That's the beginning, day 1, and 7 days after that is "week 1" I then create the journal entry, I consolidate anything previous to these 7 days like setup and germination techniques/time "soaking, paper towel ext" into this first week despite it being older then the 7 days. I do this because some seeds can take forever to pop and I feel the time line gets messed up. Same idea as when I'm flowering, I count it as in flowering when I switch the light schedule, a control of events, not when it starts to show flowering traits as that could be a week or two behind the initial switching of the lights. Similar mindset to being a week or so waiting for the seeds to pop.
