# WithinPastYears

**WithinPastYears** indicates **True** if two **TDateTime** values are within the specified **AYears** number of years of each other.

**WithinPastYears** is used to determine whether the date specified by **ANow** is within **AYears** years of the date specified by **AThen**.

Fractional years do not count, so if **ANow** and **AThen** are two and a half years apart, calling **WithinPastYears** with **AYears** set to 2 returns **True**.

**Declaration**: function WithinPastYears(const ANow, AThen: TDateTime; const AYears: Integer): Boolean;

An example.

```pascal
procedure OnMapEvent(var Value:Variant);
var
  TheDate, ThatDate : TDateTime;
begin
 //The IF is False as more than 10 years
  TheDate := EncodeDateTime(2023, 11, 30, 13, 25, 15, 650);
  ThatDate := EncodeDateTime(2012, 11, 29, 13, 25, 15, 650);
 if WithinPastYears(ThatDate, TheDate, 10) then
    LogInfo('The difference between the two dates is less than 10 years')
 else
    LogInfo('The difference between the two dates is more than 10 years');
end;
```
