Cron Explorer

Parse a 5-field cron expression (min hour dom mon dow) and show upcoming run times. Client-side only.

Cron expression (5 fields)

Base time (local)

How many occurrences

Supported syntax

Wildcards: *
Lists: 1,2,5
Ranges: 9-17
Steps: */15, 1-10/2

Notes: This is a pragmatic explorer for ops coordination, not a full cron spec emulator (no seconds field; no special tokens like @daily). Day-of-month and day-of-week follow typical cron OR semantics (match if either field matches when both are restricted).

Examples

*/5 * * * *   # every 5 minutes
0 9 * * 1-5    # 9:00 on weekdays
30 2 1 * *     # 02:30 on the 1st of each month
0 */6 * * *    # every 6 hours
15 3 * * 0     # Sundays at 03:15
