GETSSRD(CalcType, LawYear)

• CalcType: this indicates how Social Security Retirement Date is to be calculated as follows:
  • 0: if a person is born on January 1, use the prior year for determining the retirement age (this is the method used by the Social Security Administration).
  • 1: only look at year of birth (regardless of whether or not that Person was born January 1) when calculating SSRD.
• LawYear: the law year to be used in the determination of SSRD (see above).

• GETSSRD(0, YEAR(CALCDATE)): calculates SSRD using the method used by the Social Security Administration using the law in effect as of the calculation date.
• GETSSRD(0, MAX(1984,YEAR(CALCDATE))): calculates SSRD using the method used by the Social Security Administration always using at least the current law.
