# `Month`

A month of the year: `january` to `december`.

Use it for something that recurs each year, such as a seasonal price. For one particular month, use [`YearMonth`](/docs/types/type-year-month.md).

## Shape

One of these 12 values:

`Month.january`, `Month.february`, `Month.march`, `Month.april`, `Month.may`, `Month.june`, `Month.july`, `Month.august`, `Month.september`, `Month.october`, `Month.november`, `Month.december`.

## Example

```jadpo
Month.october
```

`text.parse(raw, as: Month)` reads one from text that comes from outside. Text that isn't one at all fails `malformed`, such as `jan`, `10` or `smarch`.

## Good to know

- `==` tells you whether two are the same. `<` and `list.sort_by` don't take it.

## In JSON

A string, in a request, a response or `json.write`:

```json
"january"
"october"
```

## Details

<details>
<summary>Text form, storage, how it is shown, and operations</summary>

`Month` is in the group Time and calendar, and has been in Jadpo since 0.1.0.

### Text form

`text.from` writes one standard text form, the same form `text.parse` reads back: `january` and `october`.

### How it is stored

It is stored in one column named for the field, of type `text`. `october` is stored as `'october'`.

### How it is shown to people

`text.format(value, locale:)` shows it to people in their locale.

With `locale: Locale.en_gb`:

| Value | Shown |
|---|---|
| `january` | `January` |
| `october` | `October` |

### Operations

It also takes `text.parse`, `text.from`, `text.format`, `json.read`, `json.write` and `==`. [How every standard type behaves](/docs/every-standard-type-meets-one-contract.md) says how they work.
