Creating a Batch Job for Executing Later

Hi Experts!

I was wondering if there was a way to create a batch job, but to have it executed at a later time, since we do not have an exact date and time we need these jobs executed. My goal is to create 12 batch jobs (1 for each month), but have them excuted, when I need them too, when I choose it. Is this even possible?. I tried looking through SM36/SM37, but could not find anything on it. Please advise and thanks in advance!
