About UK Decimalisation Day
Decimal Day in the United Kingdom was 15 February 1971, when the pound sterling was decimalised, replacing the old system of pounds, shillings and pence (240 pence to the pound) with the new decimal system of 100 pence to the pound. The changeover was the result of years of planning and public education. The old system had been in use since Anglo-Saxon times.
That was 20,120 days ago — approximately 2,874 weeks, 662 months or 55.1 years since 15 February 1971.
