Common Cron Mistakes Caught by Translation
0 2 * * *vs0 */2 * * *— "at 2 AM daily" vs "every 2 hours"* * * * 1vs0 0 * * 1— "every minute on Mondays" vs "midnight on Mondays"0 0 31 * *— only runs in months with 31 days (skips Feb, Apr, Jun, Sep, Nov)0 0 * * 7— Sunday (7 = Sunday in some implementations, 0 in others)
The Cron to Human Readable converter on TechConverter.me translates any cron expression instantly. Use it to verify schedules before deployment, add readable comments to your code, and communicate job timing to non-technical team members.
Examples
Example 1: Basic Expression Translations
The most common cron expressions and their human-readable equivalents:
* * * * *
→ "Every minute"
0 * * * *
→ "At minute 0 past every hour" (i.e., every hour on the hour)
0 0 * * *
→ "At 12:00 AM every day" (midnight daily)
0 9 * * *
→ "At 09:00 AM every day"
0 9 * * 1-5
→ "At 09:00 AM, Monday through Friday"
0 9 * * 0
→ "At 09:00 AM every Sunday"
0 0 1 * *
→ "At 12:00 AM, on day 1 of the month"
0 0 1 1 *
→ "At 12:00 AM, on day 1 of January"
Example 2: Step Values Translated
Step values (using /) are translated into "every N" descriptions:
*/5 * * * *
→ "Every 5 minutes"
*/15 * * * *
→ "Every 15 minutes"
0 */2 * * *
→ "At minute 0 past every 2nd hour"
0 */4 * * *
→ "At minute 0 past every 4th hour"
0 8-18/2 * * *
→ "At minute 0 past every 2nd hour from 8 AM through 6 PM"
*/30 9-17 * * 1-5
→ "Every 30 minutes, between 09:00 AM and 05:59 PM, Monday through Friday"
Example 3: Complex Expressions Decoded
More complex expressions that are difficult to read at a glance:
0 8 1-7 * 1
→ "At 08:00 AM, on the first Monday of the month"
(day 1-7 AND Monday = first Monday)
30 8,12,17 * * 1-5
→ "At 08:30 AM, 12:30 PM, and 05:30 PM, Monday through Friday"
0 0 L * *
→ "At 12:00 AM, on the last day of the month"
(L = last, supported in Quartz/Spring)
0 0 * * 5#3
→ "At 12:00 AM, on the third Friday of the month"
(# = nth occurrence, supported in Quartz/Spring)
0 0 1,15 * *
→ "At 12:00 AM, on day 1 and 15 of the month"
0 2 * * 6,0
→ "At 02:00 AM, on Saturday and Sunday"
