Cron Expression Parser

A cron expression parser that translates scheduling syntax into human-readable descriptions. Cron expressions like '0 9 * * 1-5' are powerful but hard to read — this tool tells you exactly when a job will run next and shows the upcoming execution schedule. The parser supports standard 5-field cron plus Quartz extensions including seconds (6-field), last day of month (L), nearest weekday (W), and specific occurrence (#). Enter your expression and see: a plain-English description, the next 5 execution times, and any syntax errors highlighted. Common scenarios: verifying a Jenkins job schedule before deploying, debugging why a cron-triggered task runs at unexpected times, or explaining a schedule to a non-technical teammate.
