Validate cron syntax, see the next 10 scheduled run times, and get a plain-English description — free, no signup, instant results.
Type a 5-field cron expression in the input box (minute, hour, day, month, weekday), or click one of the example chips below.
The tester instantly calculates the next 10 scheduled execution times and shows how long until each one fires.
Get a plain-English description of what the schedule means — no more guessing what "0 9 * * 1-5" actually does.
A cron expression is a string of 5 (or 6) space-separated fields that defines a schedule for automated tasks. The 5-field format is: minute (0–59), hour (0–23), day-of-month (1–31), month (1–12), day-of-week (0–6, where 0 = Sunday). Common symbols: * (any), */n (every n), n-m (range), a,b (list).
This expression runs every weekday (Monday–Friday) at exactly 9:00 AM. Breaking it down: minute=0, hour=9, day-of-month=any, month=any, day-of-week=1-5 (Mon–Fri). It is one of the most common schedules for business-hours jobs.
This tester supports the standard 5-field Unix cron format used by crontab, GitHub Actions, AWS EventBridge, and most schedulers. Some platforms (like Spring and Quartz) use a 6-field format with seconds as the first field — for those, remove the seconds field before testing here.
Most cron testers are hidden inside paid monitoring platforms like Cronitor or Better Stack. This standalone free tool runs entirely in your browser — no server, no account, no limit. SolutionGigs believes developer utilities should be free and accessible to everyone.
