cron.schedule('0 9 * * 1-5', fn) returns a invalid Next Run date #482
Description
I have set up a cron job that's supposed to run on weekdays at 9AM
const nineAmJob = cron.schedule('0 9 * * 1-5', async () => {
logger.info("Starting 9 AM Job");
...
logger.info("Completed 9 AM Job");
logger.info(`Next run will be ${nineAmJob.getNextRun()}`)
});
const status = nineAmJob.getStatus();
const nextRun = nineAmJob.getNextRun();
logger.info(`Successfully started service, status is ${status}`);
logger.info(`Next run will be: ${nextRun}`)
Today is Fri Aug 08 2025
it worked fine today in the morning but now it's returning a next run date of Mon Sep 01 2025 09:00:00 GMT-0400
I expect the next run date to be Mon Aug 11 2025 09:00:00 GMT-0400
From what i've tried it seems like the day of the month is interpreted as 1 when using a wildcard, when i set it to 0 9 11 * 1-5 it does return the next Monday
here are the logs of todays run in the morning
