Frequently Asked Questions
Everything you need to know about Cron expressions, syntax rules, and platform nuances.
Why can some Cron expressions not convert directly 1-to-1 between dialects?
Different dialects have distinct features: standard Linux cron lacks second precision (which Spring provides) and does not understand Quartz modifiers like "L", "W", or "#". When converting, our engine explains exactly what adjustments or trade-offs were made.
How does converting from Linux Cron to Quartz handle the wildcard rule?
Quartz strictly requires a "?" in either Day-of-Month or Day-of-Week. The converter automatically inspects your input and replaces "*" with "?" in the unconstrained field to ensure strict Quartz parser compliance.
