VBA have a sub run another sub

how to run a sub stored in another worksheet's module?

worksheet1

sub endDay()
    'something here
end sub

worksheet2

sub reCalc()
    'something here
end sub

I want recalc to be able to run on its own but I want to be able to press the button for "endDay", have it do its thing, and then preform "recalc" at the end instead of pressing one and then go to sheet2 to press the other.

Can someone give me a sample so I can have an idea where to begin?
