This Was The Week That Was
In 2016, March 27 - April 2 Awareness Week begins on a Sunday and ends on a Saturday. It should do so again in six years unless something unusual happens.
For the years in between, March 27 through April 2 will still be a week - 7 days - so you can still celebrate the awareness thereof as usual.
You may recall that we are still in March 15 - April 14 awareness month. This week then, double your awareness efforts to celebrate both the month and the week properly.
According to Wikipedia (WDNL), the word "week" comes from the Old English word "wice". This pretty much has nothing to do with the celebration of this wice.
One thing to be aware of this week is that, if you don't celebrate it, no one is likely to care. This is one of the weakest special occasions of the year.
If you manage to find a decent way to celebrate it, please, please, please keep it to yourself.
