Term Function

Description:
This function calculates the years, months and days between two dates and includes both the start date and end date in the result.
Since the number of days varies for different calendar months, there is no perfect way of calculating term and the results may vary depending on the approach used. The Term function supports two ways of calculating the months:
  • Where the term includes a full calendar month
    , the count of calendar months is calculated before the count of days (default, parameter set to "true");
  • Where the term starts mid-month
    , the month is calculated from the start date and the length of the month is determined by the month of the start date (parameter set to "false").
In most cases, both approaches will use the same logic and produce the same result. However, there are cases where the results will differ. To illustrate the difference in these two approaches, please see the following examples.
From Date
To Date
Parameter "True" (Default)
Parameter "False"
August 20
September 29
Result: 1 month and 10 days
Result: 1 month and 10 days
August 20
September 30
Result: 1 month and 12 days
Calculation:
September 1-30 = 1 month (30 days)
August 20-31 = 12 days
Result: 1 month and 11 days
Calculation:
August 20 - September 19 = 1 month (31 days)
September 20-30 = 11 days
August 31
September 30
Result: 1 month and 1 day
Result: 1 month and 1 day
August 30
September 30
Result: 1 month and 2 days
Calculation:
September 1-30 = 1 month (30 days)
August 30-31 = 2 days
Result: 1 month and 1 day
Calculation:
August 30 - September 29 = 1 month (31 days)
September 30 = 1 day
August 31
October 15
Result: 1 month and 16 days
Result: 1 month and 16 days
August 30
October 15
Result: 1 month and 17 days
Calculation:
September 1-30 = 1 month (30 days)
August 30-31 = 2 days
October 1-15 = 15 days
Result: 1 month and 16 days
Calculation:
August 30 - September 29 = 1 month (31 days)
September 30 = 1 day
October 1-15 = 15 days

Parameter
Data Type
Description
1
Date
First day of the term
2
Date
Last day of the term
3
Text
Format of the resulting term:
"ymd" = years, months, days
"md" = months, days
"wd" = weeks, days
"d" = days
"YMD" = years, months, days, in words
"MD" = months, days, in words
"WD" = weeks, days, in words
"D" = days, in words
4
Boolean
"True" to count full calendar months before counding the days (Default)
"False" to count the months from the start date where the term starts mid-month
Examples:
When using functions inside a field, remember the field brackets:
{Term(DateFrom, DateTo, “ymd”)}
The examples below use the following dates for the calculation:
DateFrom: August 20, 2020
DateTo: September 29, 2021
Expression
Result
{Term( DateFrom, DateTo, "ymd" )}
1 year, 1 month, 10 days
{Term( DateFrom, DateTo, "YMD", false )}
one year, one month, ten days
{Term( DateFrom, DateTo, "md", true )}
13 months, 10 days
{Term( DateFrom, DateTo, "wd" )}
58 weeks
{Term( DateFrom, DateTo, "D" )}
four hundred and six days
To change the separators between the years, months and days, you can specify the format for this function.
For example: {Term( DateFrom, DateTo, "ymd" ) format ", | and |."}
