We have a program to mass delete matches in

SCHEDULE
MASS DELETE

In addition you can delete matches one by one using

SCHEDULE
MATCH LIST
DELETE

The mass delete program allows you delete matches one division at a time, either complete set of matches or just for matches with a certain status e.g. all cancelled matches.

If you wanted to delete all matches after a certain date e.g. Feb 1st then you will either have to 

delete them all one by one 

or 

use the SCHEDULE --> MASS UPDATE program to change the status to be "cancelled" first. Then use the MASS DELETE to delete all "cancelled".
