⏱Cron Expression Parser
Cron expressions are a standard format for defining recurring task schedules. They're widely used in Linux crontab, CI/CD schedules, and cloud function triggers. An expression consists of 5 fields: 'minute hour day month weekday', each supporting * (all), numbers, ranges (1-5), intervals (*/5), and lists (1,3,5). This tool converts cron expressions into human-readable descriptions and previews the next 10 execution times.
