Regulation 2(3) to (5) move the START of the period in the cases they list; none of them shortens it. This record dates the value to the amending instrument's commencement, 1 October 2006; its own regulation 1(2) also limits it to confinements expected from 1 April 2007, so no earlier maternity pay period ran for 39 weeks.",

The evidence is the pair: the 1986 Regulations' current view, where the value is today, and SI 2006/2379 as made, the frozen witness that put it there. Both are hashed into this record and recomputed at Gate 2. One value only: the 26-week period before 2006 waits for a parser that can read a block substitution.",
