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?
