A lovely little thing will happen today during the third second of the second minute of the first hour of the fifth day of the fourth month of the sixth year of this century - it will be 01:02:03 04/05/06
If you miss it, don’t worry. It will happen again on 4 May for those who write the date in the day/month/year format.
It’s nice to have second changes in mathematic silliness. It would, on the other hand, be nice to have the ability to edit down to the second at which this post was published.
