Copy/Paste based on Date Range

I would like to create a macro that will copy rows of data from one worksheet (Sheet1) and paste them in another worksheet (Sheet2), based on a date range. The column on Sheet1 containing the data's date will be Column D.

The date range will be located on a third worksheet (Sheet 3) in cells L2 (Begin Date) and L3 (End Date).

Any help would be great.
