Little Millennium Man was born on Saturday 1 ^st January 2000 and he will retire on the first Saturday 1st January that occurs after his 60 ^th birthday.

Julian Stirling of Hethersett High School made a table of the days of the week on 1 January every year from the year 2000 to the year 2100. He used the fact that the week increases by 1 day each year (why is that?) apart from immediately after a leap year when it increases by 2 days. The pattern repeats after 28 years.

The first Saturday 1 ^st January after 2060 is in 2061 so Millennium Man will retire on his 61 ^st birthday. The 1st January falls on a Saturday 4 times every 28 years. It falls on a Saturday 15 times this century so his birthday will occur on a Saturday 15 times during this century.

Well done also Lizzie Garthwaite and Hollie Jefferson, Y10 The Mount School, York and Fiona Watson, Y10 Stamford High School, Lincolnshire. Congratulations also to Katherine Llewellyn (age 7) and Rosalind Martin (age 8) Chawson First School Droitwich who told us "We made a note of which years were leap years and then counted up all the Saturdays. The first question came out as 2061 and the second came out as 15."
