The Senate Finance Committee is considering legislation to simplify retirement plan distribution rules by removing references to half-years. 

For instance: under the current code, retirement plan benefits must begin by April 1^st of the calendar year following the year in which the retiree turns 70½, and the retiree may not receive benefits before reaching the age of 59½. 

These half-year age requirements are confusing for both retirees and employers because they requires them to track dates other than dates of birth.
