    Plain English first

    Write the schedule the way you'd say it out loud. Sundial parses times, days, ordinals, and intervals into a real cron expression.

    02

    Shows its work

    Each field is broken out — minute, hour, day, month, weekday — so you can see exactly what's being claimed before you trust it.

    03

    Next ten, locally

    The next firing times are computed in your browser, in your timezone. No server round-trip — paste a cron, see when it fires.

    Built to be poked at, not sold.

    Sundial is one of several prototypes built to chase a question. The rest are on the workbench — each runs entirely in the browser, no signup, no trackers.
