How to run Node.js jobs routines

Right now I have a weekly email job that works by first checking a last_email_sent timestamp against the current time, it then uses setTimeout to schedule a routine that is exactly a week from the last_email_sent timestamp. If the process ever restarts, the setTimeout would be queued again but the interval would of course be smaller. This works for a weekly email job, but is there a better way to handle jobs in node.js? Maybe there's a module out there that can let me manage my jobs that I'm not aware of.

There's a handy module in npmjs.org called node-cron.

It'll give you more flexibility.

Many of the modules listed in the node.js wiki under "Message Queues" will help with this type of system. Being a TJ Holowaychuck fanboy, I myself would probably first look at Kue.
