Build a cron expression visually by choosing values for each field instead of memorizing the syntax. Cron is powerful but unforgiving, and a single misplaced asterisk can change a daily job into one that runs every minute. This builder lets you set the minute, hour, day of month, month and day of week using simple inputs, then assembles the correct five-field expression for you and shows a plain-English summary so you can confirm the schedule before copying it into a crontab or scheduler. It supports steps like every N minutes as well as fixed values and wildcards. Adjust the fields and copy the generated expression. Everything runs in your browser with no data sent anywhere.
