> A script day is the label on a breakdown sheet or strip showing which day of the story a scene falls on, usually written D1, N1, D2 for day or night of each story day. It lets departments match wardrobe, makeup, and props for scenes that shoot out of order, and it is not the same as a shoot day.

## Where the label goes

On the [breakdown sheet](https://storiara.com/glossary/breakdown-sheet), script day sits in the header next to D/N and page count. On a [strip](https://storiara.com/glossary/strip), it's usually a small field near the scene number. A week of the shooting schedule might look like this:

| Shoot day | Sc. | Set | D/N | Script day | Pages |
|---|---|---|---|---|---|
| 6 | 42 | EXT. GAS STATION | N | N4 | 5/8 |
| 6 | 42A | INT. GAS STATION | N | N4 | 2/8 |
| 6 | 7 | INT. ROSIE'S DINER | D | D1 | 1 2/8 |
| 7 | 61 | INT./EXT. MAYA'S VOLVO | N | N4 | 3/8 |
| 7 | 90 | EXT. QUARRY ROAD | D | D5 | 2 1/8 |

Shoot day 6 moves from story night 4 back to story day 1. That's normal. The script day column is what tells the costume trailer to put Maya back in her waitress uniform (Change 1) after she spent the morning soaked in her rain jacket (Change 6). Without it, someone has to reread the script every morning.

## How to number script days

The usual approach, done once for the whole script before scheduling:

1. Start at D1 with the first scene. If the film opens at night, start at N1.
2. Keep the same number while the story stays in the same day.
3. When day turns to night without sleep, keep the number and switch the letter: D1 becomes N1.
4. When characters wake up or the story jumps to a new day, add one: N1 to D2.
5. For flashbacks or flash-forwards, use a separate series, like FB1 or "D1 (1994)".
6. When the script gives no clue, make a call, note it, and ask the writer.

Script day numbering is really a [story day](https://storiara.com/glossary/story-day) chart turned into labels. The [script supervisor](https://storiara.com/roles/script-supervisor) builds the full timeline and often catches cases where the breakdown and the script disagree. Settle discrepancies in prep.

## Who uses it

Costume uses it to count changes in the [wardrobe breakdown](https://storiara.com/templates/wardrobe-breakdown). Hair and makeup use it for injury progression and hairstyles. Props use it for things that change over the story, like a ring that comes off after the divorce or a phone screen that cracks. The [1st AD](https://storiara.com/roles/first-assistant-director) uses it to spot days with many time jumps, since each jump can mean costume and makeup changes that eat into the shooting day.

## Common confusion

People mix up script day, shoot day, and [scene number](https://storiara.com/glossary/scene-number). Scene 90 on script day D5 on [shoot day](https://storiara.com/glossary/shoot-day) 7 involves three different numbers, all printed near each other on the call sheet. The other mistake is leaving the field blank on the breakdown sheet because "it's obvious," which it isn't to a costumer reading one strip at 5 a.m.

## Frequently asked questions

### What is the difference between a script day and a shoot day?

A script day is when a scene happens in the story. A shoot day is when the crew films it. Scenes from script day 1 might be filmed on shoot day 14 and shoot day 2.

### Is a script day the same as a story day?

Yes, most productions use the terms interchangeably. Script day tends to be the label written on breakdown sheets and strips; story day is how script supervisors and costume departments often talk about the timeline itself.

### How do you label a night that runs past midnight?

Most productions keep it on the same night number until the characters sleep or the story clearly moves to the next day. A scene at 1 a.m. after a dinner that started on N2 is still N2. Some productions break the rule when a big wardrobe or makeup change happens overnight, so write the rule you use in the breakdown notes.
