The Dating Game was a popular TV show in the 1960s and 1970s. The concept was simple. Three contestants tried to win a date with a man or woman by impressing him or her with their answers to question. The contestants were hidden and the person asking the questions knew nothing about them other than the sound of their voices and the answers they gave.
When it comes to “dates” in presentations, uncertainty is anything but funny; it can be frustrating and expensive. I’m speaking about calendar dates. Let’s take today’s date. Growing up in Canada, I learned to write June 21, 2009. Living in Switzerland, I now use the European style: 21 June 2009. Either way, the date is clear.
But what if I use only numbers? In the United States, people write 06/21/09 (or 06.21.09 or 06-21-09). In Europe and many other places in the world, they write 21/06/09. Because there are only 12 months, most people would assume that the “21” refers to the day and the “06” refers to the month of June.
However, what about the following date: 11/10/09? It could be 11 October 2009 or 10 November 2009. To complicate matters further, International Standard ISO 8601 (with which the Chinese dating system agrees) follows the order: year-month-day. While the year is usually written with four digits, it is sometimes written with only two. Thus, the example immediately above could also mean 9 October 2011.
Today, the members of our audiences frequently come from all over the world, bringing with them their own cultural biases. Furthermore, copies of our presentations travel around the world with the push of a button. It is crucial that we leave no room for error about dates. The last thing you want is a telephone call from a customer on 11 October asking where the material is when you thought you had another month to get it to him.
The best strategy is to play it safe. On your presentation material, write the month out in full and use four digits for the year. Make the date is obvious.

In the meantime, let’s return to The Dating Game and end with a flash from the past and a clip featuring a certain celebrity in his younger days.
