Date picker

Pickers are used to display past, present, or future dates or times. The kind of date (exact, approximate, memorable) you are requesting from the user will determine which picker is best to use. Each picker’s format can be customized depending on location or need.

Use date and time pickers when you are asking the user for a time or date, or for scheduling tasks.

By default, the pickers have fixed widths. If you are placing the picker inline with other inputs, such as in form, then the widths can be adjusted to match the other inputs. The picker can either increase or decrease in width as needed. If you adjust the size, be aware that pickers have minimum widths and the date content should never horizontal scroll or overflow.

The calendar itself will always remain a fixed width and is not adjustable. It should always be aligned to the left edge of its assigned text field.

For further content guidance, see Carbon’s content guidelines.

The behaviors listed in this section are universal across all of the types. For behaviors that are unique to each type, see each of the component type sections below.

Invalid fields should be clearly marked. In pickers with more than one field, the invalid state should only be set on the individual factor that is triggering the error so the user can clearly understand which to address.

Internationalization, also referred to as globalization, refers to software adapting to different languages, regional peculiarities, and technical requirements of a target locale without additional code changes. This means that if the location is known, then formatting of a date or time can automatically change to the acceptable local format. You should always try to design for internationalization.

The simple date input provides the user with only a text field in which they can manually input a date. It allows dates to be entered without adding unnecessary interactions that come with the calendar menu or a dropdown.

The simple date input can include month/year or month/day/year. The formatting may be localized and rearranged in sequence of appearance.

Simple date inputs are typically used when the date is known by the user, such as a date of birth or credit card expiration.

Simple date inputs are best for when asking the user for an approximate date instead of an exact date, especially in regards to past dates. For example, when was asking a user when a purchase was made they will most likely easily recall the month and year (November 2019) versus the specific date (November 22, 2019).

The simple date input is a text input and has the same interactive state and behaviors. See the style tab for more details.

Calendar pickers default to showing today’s date when opened and only one month is shown at a time. Calendar pickers allow users to navigate through months and years, however they work best when used for recent or near future dates. If a user needs to input a far distant or future date consider having the calendar default open to a more convenient day.

Keep in mind that some users may find calendar pickers difficult to use. There should always be a simple way to enter dates in a text field when using calendar pickers.

Use a calendar picker when the user needs to know a date’s relation to other days such as the day of the week it falls on or its proximity to today. They are optimal for scheduling tasks.

In a single date picker a user has the option to either manually input a date in the text field or select one specific date from the menu calendar. It requires a day, month, and year to be selected.

The date range picker functions much like the single date picker but instead of choosing just one date the user can choose a start and end date. For each date in the range, users have the option to manually enter the date in a text field or select the date in the calendar. Each point requires a day, month, and year to be selected.

The calendar can be opened in two ways:

A date can be selected by:

A user can navigate between the months in a year by:

By default the current date and year appears in the calendar. To navigate to another year the user can do one of the following:

The calendar can be closed in one of the following ways:

There are several ways in which a range can be selected:

In order to constrain the possible selectable dates in a calendar, a min and max date may be set. Once set, only the dates that fall within the min/max range will be selectable with the dates outside of the range being disabled.

Use min and max dates to help prevent user error. If a user cannot select dates in the past when scheduling, then set a min date to today.

Time pickers provide the user with a text field in which they can input the hour and minutes. Additionally, they can be accompanied by an AM/PM and a time zone control, both styled as selects.

The time field format should include the hour and minutes, for example 11:30. It may be localized accommodate the 12-hour or 24-hour format.

Use the time picker when a specific time needs to be scheduled, such as planning a meeting time.

Use the light prop modifier when placing date pickers on alternate backgrounds. The light prop will change the background color token of the inputs from field-01 to field-02. This is frequently used in form modals or when on a tile.

Another common use case not accounted for in the above pickers is setting a time or date relative to today or now, such as with a reminder. For example, setting an install to begin now, in one hour, or tonight. This type of picker can made by using the standard select component.

Another acceptable form of a time or date experience would be using individual inputs for each factor. Using an individual field for each factor of a date or time can help reduce formatting errors. This is especially beneficial when localization cannot be used to reformat dates.

Instead of having one input for an exact date (month/day/year), you could have three separate inputs and a clear label for each.
