Cron Expression: 5-Field crontab + Next Runs
Typical scenarios: ① check whether a cron expression is correct before scheduling a task; ② troubleshoot timing mismatches when a task doesn't run as expected; ③ explain an expression to a colleague.
How to use: enter the expression and the tool explains its meaning and lists the next few run times, so you can confirm it behaves as expected.
Notes: ① the five fields are minute, hour, day, month, weekday — supporting `*` (any), `,` (list), `-` (range), `/` (step); ② run times are based on your current timezone — verify the server timezone before deploying; ③ tasks may skip or repeat during daylight-saving transitions, so stagger critical jobs.
