You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Create a query to show the day of the week and also the day number on which each event occurred:

Events with weekday

In no particular order, this is what the output of your query should look like.

You can use the DATENAME function to get the day of the week, and the DAY or the DATEPART functions to get the day number.

Use this to show:

  • That mercifully there weren't any events on Friday the 13th;
  • That there was one event on Thursday 12th (the day before); and
  • That there were two events on Saturday the 14th (the day after).

Save this query as Friday the 13th, then close it down.
