- An integer representing the day of the month.
The number of milliseconds between 1 January 1970 00:00:00 UTC and the given date (the
Date object is also changed in place).
dayValue is outside of the range of date values for the month,
setDate() will update the
Date object accordingly.
For example if 0 is provided for
dayValue, the date will be set to the last day of the previous month.
If a negative number is provided for
dayValue, the date will be set counting backwards from the last day of the previous month. -1 would result in the date being set to 1 day before the last day of the previous month.
var theBigDay = new Date(1962, 6, 7); // 1962-07-07 (7th of July 1962) theBigDay.setDate(24); // 1962-07-24 (24th of July 1962) theBigDay.setDate(32); // 1962-08-01 (1st of August 1962) theBigDay.setDate(22); // 1962-08-22 (22th of August 1962) theBigDay.setDate(0); // 1962-07-31 (31th of July 1962) theBigDay.setDate(98); // 1962-10-06 (6th of October 1962) theBigDay.setDate(-50); // 1962-08-11 (11th of August 1962)
