National Minimum wage (NMW) a matter of months

My colleague Neel was working on a client and asked me this interesting question.

What should be NMW for an employee who is 20 years and x months old.

NMW is given in terms of whole years like

25 years and over                            £7.83

21 to 24                                                £7.38

18 to 20                                                £5.90

As always HMRC has been kind enough to make a manual about NMW and share it with us.

See link NMWM03050.

Its states that the worker should be paid £5.90 till he reaches his 21^st birthday.
