Macro to copy rows from one sheet to another based on selected date range

Hello experts
I am attaching herewith an Excel file which contains 5 sheets.

It contains a sheet called Periodic Data. In this i am entering From & To dates and click on the command button.
It copies the rows from MAST sheet where the Left Port is >=From Date and <=To date.

The code is working , but the problem is of speed.

The date range can be of 1 week , 2 week , 1 month , 6 months & so on.
The problem is greater the period, the more number of rows are to be copied and more time it takes to run the code.

Please have a look and suggest something to improve the speed.
