Much was made of the fact that at this year's fireworks in Sydney harbour, the people put the wrong date in on the display and we seemed to welcome 2018 all over again. Such mistakes are rare now. But in the past, much more than now, New Year's was often a time of confusion. Remember cheques. We had to date cheques and had to remember to change the year from one year to the next. Now with automatic banking and direct deposit, who needs to think about cheques. And remember writing letters. We had to remember to change the year on letters that we wrote. Now my computer and word processing programme do that for me.
