What does this tool do?
It takes a standard 5-field cron expression and explains in plain English when it will run, then shows the next 10 actual fire times converted to your local timezone. You type a cron string like "*/5 * * * *" and immediately see "Every 5 minutes" along with timestamps for the upcoming runs. It is meant to make cron readable at a glance without trial and error or external services.
Which cron syntax is supported?
Standard 5-field cron: minute, hour, day of month, month, day of week. The fields accept stars, comma lists, ranges with a hyphen, step values like */5 or 1-30/2, and named values for months (JAN, FEB, etc.) and weekdays (MON, TUE, etc.). 6-field cron with seconds, AWS-style year fields, and Quartz extensions like ? or # are not supported in this tool.
How are day-of-month and day-of-week combined?
Following the original Vixie cron behaviour: if both fields are restricted, a date matches when EITHER condition is satisfied (an OR). If one of them is "*" the other is taken as-is. So "0 0 1 * MON" fires on the 1st of every month and on every Monday, not only Mondays that fall on the 1st.
Where does the next-runs calculation happen?
Everything runs entirely in your browser - nothing is uploaded. The tool walks forward minute by minute from now and collects the first 10 timestamps that match. The lookahead is capped at one calendar year, so very rare expressions (for example "0 0 29 2 *" - Feb 29) may show fewer than 10 entries if there are not enough matches in that window.
Why are the times in my local timezone?
Cron itself has no timezone - it runs in whatever timezone the server is configured for. Showing the next runs in your local time makes it easier to sanity-check that a job will fire when you expect. The tool labels the section with your detected timezone (for example, Asia/Kolkata), so you can mentally adjust if the production server is in UTC or another zone.
Why do I get an error like "Range out of order"?
A range like "5-1" is invalid because the start is higher than the end. Cron does not wrap ranges around the end of the field. The same applies to numbers outside the field range, for example a 60 in the minute field. The tool reports these as parse errors immediately so you do not waste time waiting for a job that will never fire.
