> Day/night, abbreviated D/N, is the field on a breakdown sheet and strip that records whether a scene takes place during the day or at night, taken from the scene heading. Some productions add dawn, dusk, or magic hour. It drives strip color, call times, turnaround, and lighting needs.

## Resolving what the script actually says

Scene headings are inconsistent about time. Here's a run of five scenes and how they'd be entered:

| Sc. | Heading as written | D/N entered | Reason |
|---|---|---|---|
| 33 | EXT. RIVER ROAD - DUSK | Dusk | short window, flagged |
| 34 | INT. HENDERSON HOUSE - FOYER - NIGHT | N | as written |
| 35 | INT. HENDERSON HOUSE - STAIRWAY - CONTINUOUS | N | continues 34 |
| 36 | EXT. HENDERSON HOUSE - LATER | N | action has porch light on, headlights |
| 37 | INT. SHERIFF'S OFFICE - MORNING | D | morning is day |

Scene 36 is the one that catches people. LATER could mean an hour or a day, and only the action lines tell you. When the text doesn't settle it, ask the writer or director and write the answer in the notes.

## Why it matters so much for scheduling

Night exteriors are expensive and slow. They need lighting packages, generators, and condors, and they wreck the crew's sleep. The [1st AD](https://storiara.com/roles/first-assistant-director) groups them into night weeks and plans the flip back to days, because [turnaround](https://storiara.com/glossary/turnaround) rules make it hard to go from a night wrap to a morning call. D/N also sets strip color on the [stripboard](https://storiara.com/glossary/stripboard) along with [INT./EXT.](https://storiara.com/glossary/int-ext).

Dusk and dawn scenes get special treatment. Usable dusk light often lasts well under an hour, depending on latitude and season, so anything beyond a short scene may take more than one evening at that light. Use a [sunrise and sunset planner](https://storiara.com/tools/sunrise-sunset-planner) to see the actual window at your location and date.

## Day/night in the story timeline

D/N also matters for continuity. The [script supervisor](https://storiara.com/roles/script-supervisor) combines it with the sequence of scenes to count [story days](https://storiara.com/glossary/story-day): D1, N1, D2, and so on. A day scene after a night scene usually starts a new story day, which usually means new wardrobe. Getting a single scene's D/N wrong can shift every story day that follows.

## Common mistakes

Tagging by the last word in the heading and ignoring the action is the usual one. Another is treating INT. NIGHT as easy. An interior night scene with windows on location still has to be shot after dark or with the windows blacked out, and those two options cost very different amounts. Note which one you're planning on the [breakdown sheet](https://storiara.com/glossary/breakdown-sheet). If you're considering shooting [day for night](https://storiara.com/glossary/day-for-night), put that in the notes too, since camera, grading, and the [director of photography](https://storiara.com/roles/director-of-photography) all have to agree to it.

## Frequently asked questions

### What does D/N mean on a call sheet?

It stands for day or night and shows whether each scheduled scene plays in daylight or darkness in the story. You will see D or N (sometimes DAWN, DUSK, or M for magic hour) beside each scene.

### How do you mark a scene written as CONTINUOUS?

Look at the scene it continues from and use that scene's time. If scene 34 is NIGHT and 35 is CONTINUOUS, 35 is a night scene for the breakdown.

### Can night scenes be shot during the day?

Interiors can, if windows are blacked out or tented. Exteriors can be shot day for night with camera and grading tricks, though it rarely looks as convincing as real night work. Either choice needs to be noted on the breakdown so lighting and grip can plan.
