Use Lead Creation Date (instead of Creation Time) ir a Report

Use Lead Creation Date (instead of Creation Time) ir a Report

Hi!
 I'm trying to generate a report showing the leads created by day.

Using a summary report and grouping on Creation Time - of course, since no two leads are created at the same time, the grouping is useless. 

How might I use the Creation Time field to get Creation Date - is there even a Creation Data Field?

Thanks
