CronGen — frequently asked questions
What is a cron expression?+
A cron expression is a compact string of five fields — minute, hour, day of month, month, and day of week — that defines a repeating schedule. For example, "0 9 * * 1-5" means 9:00 AM every weekday.
Does it handle timezones and daylight saving?+
Yes. Pick any IANA timezone and the next run times are computed in that zone, including daylight-saving transitions. It defaults to your browser's local timezone.
Are seconds and @shortcuts (like @daily) supported?+
Standard 5-field cron is fully supported, and common shortcuts like @daily, @hourly, and @weekly are understood too. Six-field expressions with seconds are also parsed where the runner supports them.
Is my expression sent to a server?+
No. Everything is computed in your browser — the expression you type and the run times never leave your device.
