i need a mocro to check if its the last day of the month and if so del
contents in cell a1


for example

chek if day = 31 then del range a1. if only 30 days in month then
chek if day = 30 then del range a1. if only 28 days in month then
chek if day = 28 then del range a1. if non of above then nothing

it can use the system date to chek what month is the current month
