The function UPDATE_DAY changes the day described by a Date or DateTime into another specified number.

This function takes two pieces of input: a Date or a DateTime, and a Number. It outputs the given Date or Datetime with the day value replaced by the given number.

Declaration

UPDATE_DAY(datetime, new_day) -> new_datetime
UPDATE_DAY(date, new_day) -> new_date

 

Parameters

datetime (type: DateTime)
Any DateTime.
date (type: Date)
Any date.
new_day (required, type: Number)
The new day; this is the number that will replace whatever value is currently associated with the day in the given Date or DateTime.

Return Values

new_datetime (type: DateTime)
The DateTime that results from taking the given DateTime and replacing the day value with the given number.
new_date (type: Date)
The Date that results from taking the given Date and replacing the day value with the given number.

Examples

Assume the first example has access to the following DateTime value:

example_date_and_time = {
"date": {
"day": 1,
"month": 4,
"year": 2021
},
"time": {
"hour": 16,
"minute": 14,
"second": 38,
"millisecond": 0
},
"timeZone": "UTC"
}

The following example takes the date described in example_date_and_time and replaces the given day value (1) with 16. Note that the only difference between the output of this example and example_date_and_time is the the value of the day. When given a DateTime as input, UPDATE_DAY returns a DateTime:

UPDATE_DAY(example_date_and_time, 16) = {
"date": {
"day": 16,
"month": 4,
"year": 2021
},
"time": {
"hour": 16,
"minute": 14,
"second": 38,
"millisecond": 0
},
"timeZone": "UTC"
}

The above example demonstrates how the UPDATE_DAY function behaves when given a DateTime as input. In order to further establish how the UPDATE_DAY function behaves when given a Date as input, assume the last example has access to the following Date value:

example_date = {
"day": 1,
"month": 4,
"year": 2021
}

The following example takes the Date described in example_date and replaces the given day value (1) with 16. Note that the only difference between the output of this example and example_date is the the value of the day. When given a Date as input, UPDATE_DAY outputs a Date:

UPDATE_DAY(example_date, 16) = {
"day": 16,
"month": 4,
"year": 2021
}
