A macro to save and close the file at a pre-defined time

Dear all,

I'm looking for a macro which can save and close the file (where the macro is put) at some pre-defined time. Is there any available or easy to make? I can open the file myself, and I just want the file to be saved and closed automatically thanks to the macro.

Basically, I use a computer to download data. As the computer is shared among my colleagues, I need to do the download in the evening. A macro can really help me, without I having to stay in the office waiting for the data download to finish.

Thank you

Thanks, GC Excel. This works perfectly
