Frequently asked questions
Does this support Hangfire and Quartz.NET?
Yes. Standard mode targets common 5-field cron and Quartz mode accepts seconds plus five schedule fields.
Are next run times UTC?
The preview uses your browser's local timezone. Verify the timezone configured by your scheduler before deployment.
Does it support every cron dialect?
No. It intentionally supports common schedules and reports unsupported or invalid expressions instead of guessing.
