schedule.interval support cron expressions

[jlosito]

I would like the ability to schedule dependabot, schedule.interval, on more options other than daily, weekly, and monthly.

For my use case specifically, I am looking for schedule it quarterly and semi-annually.

Rather than adding options quarterly and semi-annual, I believe it would be much better if dependabot were allowed to be scheduled using a cron expression to make it more generic. This would allow users to schedule it all kinds of different ways that better fit the user's needs.

Thanks for the idea.

I have an similar issue as #2038 as I want to run it "biweekly".
Support on cron would be must appreciated.

biweekly/fortnight is a pretty useful interval because many companies do 2-week sprints.
But I think cron is a much better and more flexible option.
I would suggest having schedule.cron property and fail if schedule.interval also present

Are there any updates regarding this? People have been asking for more scheduling options for years now. I have seen people ask for the ability to:

1. Run it every weekday, but on a different schedule than Monday-to-Friday, as some countries have different working days in a week.
2. Run it bi-weekly (every fortnight), to better conform to 2-week sprints which are commonplace when following SCRUM.
3. Run it every day of the week, that is, on both weekdays and weekends.
4. Run it quarterly or bi-annually, to avoid spam. Useful for projects that see little development but still need to be kept up to date.
5. Run it on certain days of the week. For example, on every weekday except for Friday because the developers don't like updating dependencies on Fridays or because the company has a 4-day workweek and Fridays are not working days.

These reasons for wanting more customizability are only the ones I have seen. I'm sure there are more.

In the project I'm working on, we have some shared libraries, pipelines etc. If updates are running monthly then services are not getting the most recent shared library if that one was updated too on the same day. So scheduling would allow to bump versions in shared repositories a week before services update.
