Listening for years
Be careful when listening for years: it is normal to treat the first two numbers and the last two numbers separately, but there are various ways of saying them. In general, speakers try to use the shortest way possible, for example, 1979 (nineteen seventy-nine), 2003 (two thousand and three), 1805 (eighteen o five). Sometimes we add mid-before a certain year, e.g. mid-2008. We also use expressions like the early/late 1980s.
P36 A2

Viewing charts
