About CronSuite

CronSuite is a small set of tools for cron schedules. The first one — the generator on the home page — lets you build an expression by choosing a schedule, reads it back in plain English, and shows the next runs on your own clock.

Every calculation happens in your browser. There is no account, no upload and no server-side processing of what you type: the page loads as static files, and the cron engine runs locally in the tab.

How it is built

The site is a static Astro build with one small JavaScript island. Scheduling comes from cron-parser, and the plain-English descriptions from cronstrue. The engine is verified against a second, independent implementation before every release.

What is here now

The generator, a parser that reads any five-field expression field by field, one indexed page per common schedule, a page of the mistakes cron lets you make quietly, and a converter for the six-field expressions that Quartz, Spring and the Node schedulers use. A validator and a timezone helper are still to come — the list lives on the home page.
