What cron format is supported?

Standard 5-field cron: minute (0-59), hour (0-23), day of month (1-31), month (1-12), day of week (0-7, where both 0 and 7 are Sunday). Quartz 6-field cron (with seconds) is not supported.

How are step values calculated?

*/5 in the minute field means "every 5 minutes". 10-30/5 means "every 5 minutes between minute 10 and 30". The parser enumerates all matching values.

Are named months and weekdays supported?

Yes. You can use abbreviated names: JAN-DEC for months and SUN-SAT for weekdays. They are converted to their numeric equivalents before parsing.
