Build or inspect five-field cron expressions with UTC examples.

How it works and limits

Numeric five-field cron: wildcards, lists, ranges and steps. No seconds, year, names, @macros, L, W, ? or # syntax. Both restricted day fields use OR; otherwise both must match. Next five UTC matches are searched within one year. No timezone/DST simulation or scheduling occurs. Verify your scheduler’s dialect before use.
