How to Build & Decode Cron Schedule Expressions
Generate 5-field and 6-field crontab schedules with instant plain English translations and upcoming trigger dates.
Build or Paste Cron Expression
Use the interactive visual builder controls for Minutes, Hours, Days, Months, and Weekdays, or paste any 5/6-field crontab string.
Instant Plain English Translation
Our schedule parser instantly decodes cryptic cron symbols into clear, human-readable English sentences.
Predict Triggers & Copy Code
View upcoming 10 execution trigger timestamps (Local & UTC) and copy production-ready code snippets for Node.js, Python, or AWS.
Standard Crontab Schedule Expressions Reference
Understand how crontab wildcard symbols parse into clear, human-readable schedule intervals.
| Schedule Type | Cron Expression (5 Fields) | Human Translation | Primary Use Case |
|---|---|---|---|
| Every 15 Minutes | */15 * * * * | At every 15th minute | Frequent polling, API syncs, queue processing, or background health checks |
| Daily at 9:00 AM (Weekdays) | 0 9 * * 1-5 | At 09:00 AM, Monday through Friday | Automated business reports, daily notification emails, or morning database backups |
| Every Sunday at Midnight | 0 0 * * 0 | At 12:00 AM, only on Sunday | Weekly log archiving, system cleanup tasks, or database index re-building |
| First Day of Every Month | 0 0 1 * * | At 12:00 AM, on day 1 of the month | Monthly subscription billing runs, invoice generation, or monthly data aggregation |

Frequently Asked Questions
About Cron Expressions
Everything you need to know about 5-field and 6-field cron expressions, Linux crontab syntax, execution predictions, and browser privacy.
100% Confidentiality
All cron parsing & schedule predictions run locally on your computer. Zero text bytes touch any external server.
Use the visual builder tabs to select desired intervals for Minutes, Hours, Day of Month, Month, and Day of Week. The tool instantly generates a valid 5-field cron string (e.g., '0 9 * * 1-5') with a plain English translation.
Paste any standard 5-field (Linux crontab) or 6-field (Quartz / Spring) cron string into the pattern bar. Our parser translates it into human-readable text and predicts the exact upcoming execution trigger dates.
The 5 fields represent: 1) Minute (0-59), 2) Hour (0-23), 3) Day of Month (1-31), 4) Month (1-12 or JAN-DEC), and 5) Day of Week (0-6 or SUN-SAT, where 0 and 7 are Sunday).
We provide instant copy-ready code snippets for Linux Crontab, Node.js (node-cron), Python (APScheduler / Celery), Go (robfig/cron), Java (Quartz), and AWS EventBridge Rule expressions.
No! All cron parsing, date predictions, plain English translations, and code snippet generation execute 100% locally inside your browser's JavaScript engine. Zero data is sent to external servers.
