The engine simulates cron recurrence rules into the future, providing the exact next 5 to 10 scheduled triggers in your local timezone and UTC.
Q. How does it translate cron into human language?
An integrated translation engine decomposes complex step values (*/15), ranges (1-5), and lists (MON,WED,FRI) into clear, natural English sentences.
