Note: A DateTime data type must contain both date information and time information. Applying a DateTime operator to a DateTime attribute should always produce a result. Be sure to use the data type that suits your needs.

Corticon.js's DateTime attribute operators that enable date-only or time-only comparison are as follows:

	Name and Syntax	Returns	Description
Is same date
	<`DateTime1`>.isSameDate (<`DateTime2`>)	Boolean	Returns a value of true if DateTime1 is the same as DateTime2, ignoring the time part.
After date
	<`DateTime1`>.afterDate (<`DateTime2`>)	Boolean	Returns a value of true if DateTime1 is after DateTime2, ignoring the time part.
Before date
	<`DateTime1`>.beforeDate (<`DateTime2`>)	Boolean	Returns a value of true if DateTime1 is before DateTime2, ignoring the time part.
Is same time
	<`DateTime1`>.isSameTime (<`DateTime2`>)	Boolean	Returns a value of true if DateTime1 is the same as DateTime2, ignoring the date part.
After time
	<`DateTime1`>.afterTime (<`DateTime2`>)	Boolean	Returns a value of true if DateTime1 is after DateTime2, ignoring the date part.
Before time
	<`DateTime1`>.beforeTime(<`DateTime2`>)	Boolean	Returns a value of true if DateTime1 is before DateTime2, ignoring the date part.

Corticon.js's DateTime attribute operators are as follows:


	Name and Syntax	Returns	Description
Equals (used as a comparison)
	<`DateTime1`> = <`DateTime2`>	Boolean	Returns a value of true if <`DateTime1`> is the same as <`DateTime2`>, including both the Date and the Time portions
Equals(used as an assignment)
	<`DateTime1`> = <`DateTime2`>	DateTime	Assigns the value of <`DateTime2`> to <`DateTime1`>
Not Equal To
	<`DateTime1`> <> <`DateTime2`>	Boolean	Returns a value of true if <`DateTime1`> does not equal <`DateTime2`>
Less than
	<`DateTime1`> < <`DateTime2`>	Boolean	Returns a value of true if <`DateTime1`> is less than <`DateTime2`>
Greater than
	<`DateTime1`> > <`DateTime2`>	Boolean	Returns a value of true if <`DateTime1`> is greater than or equal to <`DateTime2`>
Less than or Equal to
	<`DateTime1`> <= <`DateTime2`>	Boolean	Returns a value of true if <`DateTime1`> is less than or equal to <`DateTime2`>
Greater than or Equal to
	<`DateTime1`> >= <`DateTime2`>	Boolean	Returns a value of true if <`DateTime1`> is greater than or equal to <`DateTime2`>
In (Range)
	`attributeReference` in `[ \|(rangeExpression)\|]`	Boolean	Returns a value of true if `attributeReference` is in the range of DateTime values `from..to`, and where opening and closing parentheses `( )`indicate exclusion of that limit and brackets `[ ]` indicate inclusion of that limit.
In (List)
	`attributeReference` in `{listExpression}`	Boolean	Returns a value of true if `attributeReference` is in the comma-delimited list of literal values, defined enumeration values, or - if in use - enumeration labels.
Year
	<`DateTime`>.year	Integer	Returns the century/year portion of <`DateTime`> as a four digit Integer
Month
	<`DateTime`>.month	Integer	Returns the month in <`DateTime`> as an Integer between 1 and 12
Day
	<`DateTime`>.day	Integer	Returns the day portion of <`DateTime`> as an Integer between 1 and 31
Hour
	<`DateTime`>.hour	Integer	Returns the hour portion of <`DateTime`>. The returned value is based on a 24-hour clock.
Minute
	<`DateTime`>.min	Integer	Returns the minute portion of <`DateTime`> as an Integer between 0 and 59
Second
	<`DateTime`	Integer	Returns the seconds portion of <>.sec `DateTime`> as an Integer between 0 and 59
Add years
	<`DateTime`>.addYears (<`Integer`>)	DateTime	Adds the number of years in <`Integer`> to the number of years in <`DateTime`>
Add months
	<`DateTime`>>.addMonths (<`Integer`>)	DateTime	Adds the number of months in <`Integer`> to the number of months in `<DateTime>`
Add days
	<`DateTime`>.addDays (<`Integer`>)	DateTime	Adds the number of days in <`Integer`> to the number of days in <`DateTime`>
Add hours
	<`DateTime`>.addHours (<`Integer`>)	DateTime	Adds the number of hours in <`Integer`> to the number of hours in the Time portion of <`DateTime`>
Add minutes
	<`DateTime`>.addMinutes (<`Integer`>)	DateTime	Adds the number of minutes in <`Integer`> to the number of minutes in the Time portion of <`DateTime`>
Add seconds
	<`DateTime`>.addSeconds (<`Integer`>)	DateTime	Adds the number of seconds in <`Integer`> to the number of seconds in the Time portion of <`DateTime`>
Years between
	<`DateTime1`>.yearsBetween (<`DateTime2`>)	Integer	Returns the Integer number of years between <`DateTime1`> and <`Date2`>. This function returns a positive number if <`DateTime2`> is later than <`DateTime1`>.
Months between
	<`DateTime1`>.monthsBetween (<`DateTime2`>)	Integer	Returns the Integer number of months between <`DateTime1`> and <`DateTime2`>. If the month and year portions of `<DateTime1>` and <`DateTime2`> are the same, the result is zero. This function returns a positive number if <`DateTime2`> is later than <`DateTime1`>.
Days between
	<`DateTime1`>.daysBetween (<`DateTime2`>)	Integer	Returns the Integer number of days between <`DateTime1`> and <`DateTime2`>. If the two dates differ by less than a full 24-hour period, the value is zero. This function returns a positive number if <`DateTime2`> is later than <`DateTime1`>.
Hours between
	<`DateTime1`>.hoursBetween (<`DateTime2`>)	Integer	Returns the Integer number of hours between <`DateTime1`> and <`DateTime2`>. If the two dates differ by less than a full hour, the value is zero. This function returns a positive number if <`DateTime2`> is later than <`DateTime1`>.
Minutes between
	<`DateTime1`>.minsBetween (<`DateTime2`>)	Integer	Returns the Integer number of minutes between <DateTime1> and <`DateTime2`>. This function returns a positive number if <`DateTime2`> is later than <`DateTime1`>.
Weeks between
	<DateTime1>.weeksBetween (<`DateTime2`>)	Integer	Returns the Integer number of weeks between <`startDate`> and <`endDate`>.
Seconds between
	<DateTime1>.secsBetween (<`DateTime2`>)	Integer	Returns the Integer number of seconds between <`DateTime1`> and <`DateTime2`>. This function returns a positive number if <`DateTime2`> is later than <`DateTime1`>.
Day of Week
	<`DateTime`>.dayOfWeek	Integer	Returns an Integer corresponding to day of the week, with Sunday equal to 1, in <`DateTime`>.
Week of Year
	<`DateTime`>.weekOfYear	Integer	Returns an Integer from 1 to 52, equal to the week number within the year in <`DateTime`>
Day of Year
	<`DateTime`>.dayOfYear	Integer	Returns an Integer from 1 to 366, equal to the day number within the year in <`DateTime`>
Week of Month
	<`DateTime`>.weekOfMonth	Integer	Returns an Integer from 1 to 6, equal to the week number within the month in <`DateTime`>. A week begins on Sunday and ends on Saturday.
To Date
	<`DateTime`>.toDate	Date	Returns the date portion only of DateTime
getMilliseconds
	`<DateTime>`.getMilliseconds	Integer	Returns the internal date/time, namely the number of milliseconds that have transpired since the epoch, 1/1/1970 00:00:00 GMT.
