About this tool
Cron Parser is a free online developer tool. Parse cron expressions to human-readable description. Built for coders and engineers who want less friction. It runs entirely in your browser — no download or sign-up needed.
Enter a cron expression (such as */5 * * * or 02 * * 1), and the tool will parse the meaning of each field and describe it in natural language (such as "every 5 minutes" or "every Monday at 2 a.m."). Displays the specific time for the next 10 executions to help verify that the expression is correct.
The parser divides the cron expression into 5 or 6 fields (time-sharing day, month, week, optional seconds) by space. Each field supports syntax such as number, range (1-5), list (1, 3, 5), step size (*/2). After parsing, a time series is generated, taking into account the number of months and leap years.
Suitable for verifying expressions when configuring scheduled tasks (such as crontab, GitHub Actions, Jenkins). It is more intuitive than consulting a syntax document, and you can immediately see the actual execution time.
Cron expression parsing tool that converts cron expressions into human-readable descriptions, displays a list of next execution times, and supports standard cron and extended syntax.
