The yearsBetween() function takes startDateTimeValue and endDateTimeValue as arguments. It returns the number of years between the given date-time values.

Note: The difference between yearsBetween function and yearsDiff function is that the yearsBetween function considers a year as 365 days. So, let's say the start date is specified as 02-Jan-2020 and the end date is specified as 01-Jan-2021, the yearsBetween function will return 1 (since the difference in days is 365). The yearsDiff function returns 0 in this case since this function considers a year depending on the number of days in it.

Return Type

  • Number


<variable> = <startDateTimeValue>.yearsBetween(<endDateTimeValue>);


<variable> = yearsBetween(<startDateTimeValue>,<endDateTimeValue>);
ParameterDescriptionData type

The starting date-time value.

A runtime error will be encountered if:

  • the hour value, or minute value, or second value, is specified in more than 2 digits

startDate = '1-Jan-2019';
endDate = '31-Dec-2019';
newStartDate = '1-Jan-2020';
newEndDate = '31-Dec-2020';
numberOfYears= yearsBetween(startDate, endDate);                         // returns 0
numOfYears = yearsBetween(newStartDate, newEndDate);               // returns 1
