Does anyone know how set a date filter so when you create a dashboard the data being shown is only data from the current date?

For instance,  If I have data in a table of the past month but when users go to view the dashboard it is filtered to only show the current days data, is there a way to set that up? 

So everyday they look at the dashboard they only see current day data, but have the option to look at historic data as well.  I would need to set something up to be able to calculate the filter to always show today's date data.

This would be a huge help!

Thanks,
