How to check when a JazzHR job was posted
JazzHR job pages carry a posted date in their structured data. The checker reads it from the page JazzHR hosts and shows it as the original posting date.
Where the JazzHR date comes from
JazzHR job pages describe the job in schema.org structured data (JSON-LD), with a datePosted. The checker reads it from the job page JazzHR hosts and shows it as "Originally posted", with the job's age. There's no updated date, so JazzHR results don't include a "Last updated" line.
The same data has a validThrough date. On both JazzHR postings we checked, it was exactly 90 days after the posted date. That looks like an expiry JazzHR puts on every listing, not a date the employer picked, so don't read it as the last day to apply.
The checker doesn't show that listing expiry. Once it has passed, the checker treats the listing as expired and shows "Closed or no longer listed".
If the job is closed or missing
JazzHR doesn't answer a missing job with a 404. It redirects, and the checker reads where the redirect goes. A redirect to the company's job list means the job is gone, and you'll see "Closed or no longer listed".
A redirect to JazzHR's home page means the company name in the link wasn't found. That says nothing about the job, so the checker shows "Posting date unknown".
Some JazzHR sites sit behind a security service that turns away automated requests like the checker's. When that happens the check ends in an error instead of a date. You can still open the link in your browser and read the page yourself.
How to spot a JazzHR job
JazzHR postings are at {company}.applytojob.com/apply/{code}, often followed by the job title, or at {company}.applytojob.com/apply/jobs/details/{code}. Both point to the same job.
Check a JazzHR link
Paste the company's apply link into the Job Age Checker. Don't use a LinkedIn or Indeed link. The checker refuses those.
