| 1.01 | Ivaylo Barakov | 22-Jul-2022 | Edit "Custom display format" section |
A date time input is an input field that lets you set and edit the date and time in a chosen input element. The display and input formats are customizable, as well as min and max values.
- Should provide a mask, specifying the date/time
inputFormatanddisplayFormat - Should provide a prompt symbol for customizing the unfilled parts of the mask
- Should support static symbols (literals) in the mask
- Should support all the properties/API of the igc-input element where applicable
- Should correctly manage and report its validation state, if any validation constraints or required positions are applied
- Should be supported as a component which participates in an igc-form submission
- Should support the following custom input formats
Developer stories:
As a developer I expect to be able to:
- define a mask specifying the date/time
inputFormatanddisplayFormat - use the mask as a placeholder if the property is not set
- specify the prompt character
- set predefined
displayFormatin a simple manner -short,long,medium,full - configure the editor as editable, read-only and disabled
- set a default date/time value
- specify if incrementing continues past the maximum and wraps around (by default it does) e.g. for minutes from 59 to 00 or just stays at it.
- set
minValueandmaxValueproperties which control the validity of the input - expect the editor to complete partially entered dates
- expect that the editor will clear invalid input on blur
- enable/disable the zero prefixes for dates/months/hours e.g. 9:03 or 09:03
- specify the step -
spinDelta, at which the selected time part will be incremented/decremented
End user stories:
As an end user, I want:
- To be able to display date/time values based on a defined mask
- To be able to edit the date/time value in the editor
- To be able to paste or drag-and-drop dates from elsewhere into the input
- The fields that need to be filled, to be clearly indicated with prompt characters
- To see a placeholder text when the input is empty, suggesting me what to type in
- The editor to handle partial dates
- The editor to have buttons for incrementing/decrementing the currently selected date/time portion
- To be able to use the mouse wheel to spin date/time portions. The spinning should occur for the date/time portion where the caret currently is in the editor
A date time input is a text field that allows the user to set and edit the date and time in a chosen input element, controlled and filtered by a predefined mask. Helper text, placeholders, and visual states can be updated accordingly upon string input/interaction and data can be submitted.
| Format | Description |
|---|---|
d |
Date, will be coerced with a leading zero while editing. |
dd |
Date with an explicitly set leading zero. |
M |
Month, will be coerced with a leading zero while editing. |
MM |
Month with an explicitly set leading zero. |
yy |
Short year format. |
yyyy |
Full year format. |
h |
Hours in 12-hour format, will be coerced with a leading zero while editing. |
hh |
Hours in 12-hour format with an explicitly set leading zero. |
H |
Hours in 24-hour format, will be coerced with a leading zero while editing. |
HH |
Hours in 24-hour format, with an explicitly set leading zero. |
m |
Minutes, will be coerced with a leading zero while editing. |
mm |
Minutes with an explicitly set leading zero. |
tt |
AM/PM section for 12-hour format. |
The date time input exposes predefined formats for displaying date/time in various manners. All of the examples below are given in en-US locale.

Furthermore, users can construct a displayFormat string using the supported symbols described in the following table.
| Type | Format | Description | Example |
|---|---|---|---|
| Day of month | d |
Minimum digits. | 7, 17 |
dd |
Zero padded. | 07, 17 | |
| Month | M |
Minimum digits. | 3, 10 |
MM |
Zero padded. | 03, 10 | |
MMM |
Abbreviated | Oct | |
MMMM |
Wide | October | |
MMMMM |
Narrow | O | |
| Year | y |
Numeric | 2022 |
yy |
Two digit | 22 | |
yyy |
Numeric | 2022 | |
yyyy |
Numeric | 2022 | |
| Hour 1-12 | h |
Minimum digits | 1, 12 |
hh |
Zero padded | 01, 12 | |
| Hour 1-24 | H |
Minimum digits | 1, 23 |
HH |
Zero padded | 01, 23 | |
| Minute | m |
Minimum digits | 1, 59 |
mm |
Zero padded | 01, 59 | |
| Second | s |
Minimum digits | 1, 59 |
ss |

| Time Period | t |
Abbreviated | AM, PM |
tt |
Abbreviated | AM, PM | |
ttt |
Short | noon | |
tttt |
Long | noon | |

Note: Many locales use the same time period string, irrespective of the format specified. Also, it has an effect only if a 12-hour clock is used.
