date-fns/addHours.d.ts

Modern JavaScript date utility library

import type { ContextOptions, DateArg } from "./types.ts";
/**
 * The {@link addHours} function options.
 */
export interface AddHoursOptions<DateType extends Date = Date>
  extends ContextOptions<DateType> {}
/**
 * @name addHours
 * @category Hour Helpers
 * @summary Add the specified number of hours to the given date.
 *
 * @description
 * Add the specified number of hours to the given date.

 * **You don't need date-fns\***:
 *
 * Temporal has a built-in `add` method on all its classes:
 *
 * - [`Temporal.Instant.prototype.add()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Temporal/Instant/add)
 * - [`Temporal.PlainDate.prototype.add()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Temporal/PlainDate/add)
 * - [`Temporal.PlainDateTime.prototype.add()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Temporal/PlainDateTime/add)
 * - [`Temporal.PlainTime.prototype.add()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Temporal/PlainTime/add)
 * - [`Temporal.PlainYearMonth.prototype.add()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Temporal/PlainYearMonth/add)
 * - [`Temporal.ZonedDateTime.prototype.add()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Temporal/ZonedDateTime/add)

 *
 * @typeParam DateType - The `Date` type, the function operates on. Gets inferred from passed arguments. Allows to use extensions like [`UTCDate`](https://github.com/date-fns/utc).
 * @typeParam ResultDate - The result `Date` type, it is the type returned from the context function if it is passed, or inferred from the arguments.
 *
 * @param date - The date to be changed
 * @param amount - The amount of hours to be added
 * @param options - An object with options
 *
 * @returns The new date with the hours added
 *
 * @example
 * // Add 2 hours to 10 July 2014 23:00:00:
 * const result = addHours(new Date(2014, 6, 10, 23, 0), 2)
 * //=> Fri Jul 11 2014 01:00:00
 *
 * @example
 * // Using Temporal:
 * // Add 2 hours to 10 July 2014 23:00:00:
 * Temporal.PlainDateTime.from("2014-07-10T23:00:00")
 *   .add({ hours: 2 })
 *   .toString();
 * //=> "2014-07-11T01:00:00"
