var sched = later.parse.recur().on(10).minute().on(8).hour()

is there any way to get cron sting like "10 8 * * *" from shedule above?

No, there has been talk of various people implementing this but I don't think anything has come from it. Being an API for generating cron statements was never a goal (the fact that it supports cron at all is kind of a fluke, personally I've never even used that functionality).

Sad to see this issue is closed. For the life of me I cannot find a library that converts natural language to cron strings. This library is sooo close.

@krazyjakee a few years ago, I managed to get something working using https://github.com/azza-bazoo/prettycron

It was able to take strings like " 25 12 *" and convert it to a cron job, and it would display the schedule in human-readable form "Every minute on the 25th in December"

It was able to handle anything thrown at it, and got a lot of love at RSA that year when it was part of the demo for the company I was with at the time.

Using the nextRun function, it could also display to the user when the next run would happen... it was pretty easy if I remember right.

Check it out! Hope this helps!

I'm looking for the opposite. To take a human readable string and output a Cron string like in this issue description.
