The cron syntax is very nice, but what if I need to check for something running at 12:00 and 17:30 ? AFAIK this can't be done with the regular cron syntax and in a crontab I would have two lines. A solution would be to have mutiple schedules enabled for one check.

Great software by the way, very easy and useful.

I would also love to see this additional feature. For some tasks, I have different schedules during the week and on the weekend. It would be great if these different schedules could be set up for the same job.
For automatic pings, it would be possible to just set up several jobs. Even though this would have the disadvantage that not all the information about the same job is at one place, it would be somehow possible. However, I have some tasks where the pings can also be triggered manually. For those, setting up several jobs would mean that one also has to know exactly which ping to trigger.

So it would be really nice if there was a "add schedule" button with which one could just add several "cron like" lines with different schedules and different grace periods for the same job.

What about https://stackoverflow.com/questions/11914445/run-a-cron-job-every-minute-only-on-specific-hours?

For example:

It will only check every minute from 11AM to 12AM, 4PM to 5PM and 9PM to 10PM

* 11,16,21 * * *

This is now possible with OnCalendar schedules: https://blog.healthchecks.io/2023/12/oncalendar-schedules-monitor-systemd-timers-with-healthchecks-io/
