Turn any cron expression into a schedule you can read. Give this actor one or more standard cron expressions and it returns the next run times, a plain-English meaning, the weekday for each run, and the previous run, all in a clean table. No API key, no sign-up, pure offline computation.
What it does
Cron syntax is compact but hard to read at a glance. Does */15 9-17 * * 1-5 fire when you think it does? This actor answers that. For each expression it validates the syntax, describes it in words, and lists the next N times it will fire from a start moment you choose, in the timezone you choose.
Input
- Cron expressions: one or more 5-field cron strings, for example
0 9 * * 1-5. - Number of upcoming runs: how many future run times to compute per expression, 1 to 100.
- Start date: an ISO datetime to compute from. Empty means now.
- Timezone: an IANA timezone name such as
Europe/Paris. Defaults to UTC.
Output
One row per computed run, with these fields:
- cron_expression: the input expression.
- description: plain-English meaning, for example "At 09:00 AM, Monday through Friday".
- valid: whether the expression parsed.
- timezone: the timezone used.
- run_number: 1 for the next run, 2 for the one after, and so on.
- next_run: ISO datetime of that run.
- weekday: day name of the run.
- seconds_from_start: seconds between the start moment and the run.
- previous_run: the most recent past run, on the first row of each expression.
- error: the reason an expression failed, when it did.
Common expressions
0 9 * * 1-5weekdays at 9am.*/15 * * * *every 15 minutes.0 0 1 * *midnight on the first of each month.0 */6 * * *every 6 hours.
Notes
Standard 5-field cron only. Computation is offline and deterministic, so runs are fast and never break on a network hiccup.
