About When This Job Was Posted?
How It Works
Paste any job listing URL and the tool cross-references multiple data sources to find the real posting date. This helps you spot ghost jobs, reposted listings, and refreshed postings that appear newer than they actually are.
Data Sources (checked in order)
- ATS API Data — If the job is hosted on a supported applicant tracking system (see table below), we query the ATS API directly for the original posting date, job title, company, and metadata.
- Page Metadata & Regex — We scan the page's HTML for dates in common formats like
datePosted,published_at, and other patterns used by job boards. - Structured Data (JSON-LD) — Many job boards include JobPosting schema for search engines. We extract the official
datePostedfield. - Open Graph Tags — We check for
article:published_timeand similar social sharing metadata. - Sitemap Lookup — As a fallback, we check the site's
sitemap.xmlforlastmoddates associated with the job URL. - Wayback Machine — We query the Internet Archive to find when the URL was first captured. This is especially useful for detecting jobs that have been refreshed or reposted.
- Hidden Insights — We extract metadata from the page's source code that isn't displayed to visitors, such as department info, AI screening status, salary ranges, and employment type.
Conflict Detection
When dates from different sources disagree, the tool flags potential reposts. For example, if a job's listed date says "posted 2 days ago" but the Wayback Machine first saw the URL 3 months ago, it's likely been refreshed. The tool always picks the oldest date and explains why.
Supported Platforms
The tool has direct integrations with these applicant tracking systems, plus generic extraction that works on most other job sites.

Frequently Asked Questions
How do I check when a job was posted?
Paste the job listing URL into the search bar on the homepage and click "Check Date". The tool scans the page's metadata, ATS APIs, and the Wayback Machine to find the real posting date. Results appear in seconds.
What is a ghost job?
A ghost job is a job listing that appears active but is no longer being filled. Companies may keep old postings live to collect resumes, meet compliance requirements, or give the appearance of growth. This tool helps detect ghost jobs by revealing the true posting date — if a "new" listing was actually posted months ago, it may be a ghost job.
How can I tell if a job posting is old or reposted?
The tool compares dates from multiple sources. If the Wayback Machine shows the URL existed months before the listed "date posted", the job was likely reposted or refreshed. The tool flags these conflicts automatically and shows you all detected dates so you can judge for yourself.
Which job boards does this tool support?
It has direct API integrations with 9 applicant tracking systems: Greenhouse, Lever, Ashby, Workable, Oracle HCM Cloud, Gem, BambooHR, Brassring, and Paycor. For all other job sites, it uses generic extraction methods that work on most career pages.
Why can't the tool check Indeed or LinkedIn jobs?
Indeed and LinkedIn block automated access to their job pages. If you find a job on either platform, look for the "Apply" button that links to the company's own careers page — paste that URL instead for much better results.
Is this tool free?
Yes, completely free with no ads, no account required, and unlimited use. If it helps you, you can support the project on Ko-fi.
Do you store my data?
No. All search history is stored in your browser's localStorage. We don't have accounts, cookies, or any server-side storage of your searches. Anonymous usage analytics (page views and feature usage) are collected via a self-hosted analytics platform — no personal data is tracked.
How accurate are the dates?
Dates from ATS APIs (Greenhouse, Lever, etc.) are highly accurate — they come directly from the applicant tracking system's database. Dates from HTML metadata are generally reliable but can be manipulated by the employer. Wayback Machine dates tell you when the URL was first archived, which may be days after the actual posting. The tool shows all sources so you can compare.
What if no date is found?
Some job pages don't include any date information in their source code, and the Wayback Machine may not have archived the URL yet. The tool will still extract any available metadata like job title, company name, and hidden insights. You can report unsupported job boards on our Reddit community.
