Note: next-run calculation is computed by checking each step (minute/second) up to a limit. Complex expressions may hit the search cap.
If you need advanced cron parsing (named months/days, @reboot, or quartz-style), consider using a dedicated library on the server or client (e.g. cron-parser).
Sample expressions:
*/15 * * * * # every 15 minutes0 9 * * 1-5 # 9:00 on weekdays0 0 1 * * # monthly at midnight on day 10 0 * * 0 # weekly on Sundays at 00:000 8-18/2 * * * # every 2 hours between 08:00 and 18:00@daily@hourly
