Disabling dates in calendar/date field

[lpolicarpio]

Hi team,

We have a requirement to make some dates unselectable or greyed out in the date field. Is it this possible to do in ServiceNow? Do we need a custom widget for it? Any ideas/references will be greatly appreciated. 

Thank you!

It is not possible with just "configuration" but it is customizable which you might want to avoid. It also requires understanding a little bit about angularjs and how it works in the portal. 

You can use angularjs decorators to redefine the link function for the directive to change the configs that the oob datetime variable doesn't expose. Or you can for example copy the existing datetime directive to create an angular provider that you can then use as an element directive on your custom widget. With a widget variable you will have to create another variable to store the value.

Here is the datetime variable with a side by side view and a min and max date

var config = {
	format: format,
	locale: spUtil.localeMap[g_lang],
	language: spUtil.localeMap[g_lang],
	maxDate: moment("2026-02-18"),
	minDate: moment("2026-02-10"),
	sideBySide: true,
};

Here's a write up of how to use decorators

Hi @lpolicarpio 

This is not supported in ServiceNow.

You can use either UI policy or client script to do validation like if your specific date got selected, you can show error msg or alert with some message.
