When to leave
a day blank.

A blank day isn't a zero day. The visual rule we use, and how it reads in the week-so-far strip.

Three states. Logged with revenue (solid dot). Logged with zero (solid red — open but no sales). Blank (dashed outline — closed or not yet logged).

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 When should I leave a day blank?

Leave a day blank when you were closed — a Sunday, a holiday, a sick day. Log it with a zero entry only if you were open but genuinely took no revenue (rare, but it happens), and log it with real values normally otherwise. The blank means "no data for this date"; the zero means "open, took nothing" — and Statistics treats those two states very differently.

02 What does each day state look like?

On the week-so-far strip on Home, each day reads at a glance. A solid green dot is a logged, profitable day; a solid red dot is a logged day with negative EBIT; a dashed outline is blank — either closed or not yet logged; and a solid outline is a future day that hasn't happened yet. The full key is below.

  • 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 does Statistics read a blank day?

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 How do I tell "closed" from "forgot to log"?

Same visual, different meaning. A dashed dot for Saturday looks the same whether you were closed or whether you forgot to log. Context matters — today's dashed dot is a "log me" nudge; Sunday's dashed dot in a shop that's always closed Sunday is just normal.

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.
