The five segments of Cron represent minutes, hours, days, months, and weeks in sequence. First use Chinese instructions to understand the cycle, and then check the running time with time zone offset to avoid tasks being executed at the wrong time.
Only five-segment crons are supported, and no seconds, years, or Quartz extensions are supported. When both day and week are restricted, press "or" to match. Preview does not create tasks; please check with the actual scheduler for daylight saving time boundaries. Look back up to 12 years.

Shortcut key: Ctrl/⌘+Enter. Modifying inputs or options clears old results.
At 09:00 every day from Monday to Friday, the calculation result is strictly later than the starting point. This tool does not create or execute scheduled tasks.
Not supported. Only five-paragraph syntax and common ranges, lists, steps, and English month and week abbreviations are accepted; seconds, years, L, W, ?, #, or H are not accepted.
When both are restricted at the same time, press "or" to match, but they do not have to be satisfied at the same time. Daylight saving time jumps are processed using cron-parser, which may be different from other schedulers. Please check the actual platform rules.
First limit it to five Cron segments, then use cron-parser to calculate the time strictly later than the starting point, and use cronstrue to generate Chinese instructions. Looks up to 12 years into the future, returns 10 times; day and week are both limited in adoption or semantics.
