A blank day is the right state for closures — public holidays, planned days off, sick days. Distinguishing between blank and zero is the difference between "we were closed" and "we were open and made nothing", and Statistics treats them very differently.
01 The rule
Leave a day blank if you were closed — Sunday, holiday, sick day. Log it with zero if you were open but took no revenue (rare but it happens). Log it with values normally otherwise.
02 What it looks like
On the week-so-far strip on Home:
- Solid green dot — logged with positive EBIT. Day was profitable.
- Solid red dot — logged with negative EBIT. Day cost you more than it brought in.
- Dashed outline — blank. Either closed, or not logged yet (these read differently in context — today's dashed is a nudge; Sunday's dashed is normal).
- Solid outline — future day. Hasn't happened yet.
03 How Statistics reads it
Blank days are excluded from averages. They don't drag your weekly mean down, don't get flagged as your worst day, don't appear in peak/weak detection. Zero-revenue days are counted (they're real days with real fixed-cost burden).
This distinction matters most for shops with regular closed days (closed Mondays, closed Sundays). Leaving those blank keeps your weekly averages representative of your actual operating days, not your full calendar.
04 Closed vs forgot
There's no "I was closed today" toggle in nouz. The blank is the toggle. If you want to be explicit, add a closed-day reminder note as a zero-amount expense — "Closed for public holiday" — though most owners don't bother.
