# Days of the month

> List and read the days of the month a date can be aligned to.

The days of the month are the fixed set of days a date can be aligned to, each with a `day` number. You can list them and read one. This area has 2 endpoints, and all seven SDKs call every one.

## At a glance

| Endpoint | Method | Path | What it does |
| - | - | - | - |
| [List days of the month](https://exsited.mintlify.site/api-reference/days-of-the-month/list-days-of-the-month.md) | GET | `/settings/day_of_month` | Returns a page of the days of the month a date can be aligned to, under `data`. |
| [Retrieve a day of the month](https://exsited.mintlify.site/api-reference/days-of-the-month/retrieve-a-day-of-the-month.md) | GET | `/settings/day_of_month/{day_of_month_id}` | Returns one day of the month by its `dom_` `id`, under `day_of_month`. |

## Before you call

Register your API credentials once when your app starts, as shown in
[Authentication](https://exsited.mintlify.site/authentication.md). Every SDK sample on these pages then gets its client in one line.
With cURL, send the access token in an `Authorization` header: `Authorization: Bearer $ACCESS_TOKEN`.

## Things to know

* **This area is read only.** There are no create, update or delete calls.
* **A day of the month `id` starts with `dom_`.** A single read returns the record under `day_of_month`.
* **`day` holds the day number.** It is an integer.
* **Listings page by cursor.** Records sit under `data`; pass `pagination.next_cursor` as `cursor` to read the next page, and stop when `pagination.has_more` is `false`.
