Small, useful tools for the web.
PlatformOwn builds and hosts free web tools that answer one question properly, alongside custom web applications for clients. Everything below is live and free to use — no sign-up, no account.
Free tools
Each of these takes a question people genuinely search for and answers it with a real calculation, rather than dumping a table of raw data.
Long Weekend Finder
Every upcoming long weekend in your country, plus the single day of leave that turns a three-day break into four. Covers nationwide public holidays for 205 countries, with a hand-maintained gazetted calendar for India.
Open the long weekend finder →Meeting Time Planner
The working hours two cities actually share, shown in your own clock. Handles daylight saving and half-hour timezones, and when there is no overlap at all it still gives you the least-bad times to call.

PlatformOwn also builds and hosts web applications for clients, covering the front end, the API and deployment.
Insurance OS
An internal operations tool, built and hosted on our own infrastructure.
Visit site →About
PlatformOwn is an independent web development studio. We build web applications for clients and publish free tools of our own, all running on our own infrastructure: containerised applications behind nginx, deployed through a pipeline that tests each release before it goes live.
The tools are static sites — every page is generated ahead of time, so they load quickly and keep working even when an upstream data source is unavailable.
Get in touch
Whether it's a project enquiry, a correction to a holiday date, or a bug in one of the tools — email is the fastest way to reach us. Pick whichever fits and your mail app will open with the subject filled in.
Prefer your own mail app? contact@platformown.com — we aim to reply within two working days.
If you spot a holiday or timezone that looks wrong, please do tell us — the tools are only as good as the dates behind them, and corrections from people on the ground are the fastest way we find mistakes.
Privacy Policy
Last updated: 15 August 2026
This policy explains what information is collected when you visit platformown.com and the tools hosted on its subdomains.
Information we collect
We do not ask you to create an account, and we never collect payment details. Our web server keeps standard access logs, which record the requested page, the time of the request, the browser's user agent and the IP address. These are used to keep the service running and to diagnose faults.
The contact form
If you use the contact form, we receive the name, email address and message you type into it. We use them only to reply to you. We do not add you to a mailing list, and we do not sell or share your details for marketing.
The form is delivered by Web3Forms, which relays the submission to our inbox — your message passes through their service in transit. If you would rather not use a third-party relay, email us directly at contact@platformown.com instead; the address is the same either way.
Ask us at any time to delete correspondence you have sent us, and we will.
Our tools store your preferences (such as the country or cities you last selected) in your browser's local storage. That data stays on your device and is never transmitted to us.
Cookies and advertising
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this and other sites.
- You may opt out of personalised advertising by visiting Google Ads Settings.

Third-party data
Public holiday information used by the Long Weekend Finder is retrieved from the public Nager.Date service at build time. Timezone information used by the Meeting Time Planner comes from the IANA timezone database included in your browser; no external service is contacted.
Your choices
You can block or delete cookies through your browser settings, and clear local storage at any time. Doing so will not prevent you from using the tools, though saved preferences will be lost.
Contact
For any question about this policy, contact contact@platformown.com.
Terms of Use
The tools on this site are provided free of charge and as-is. We make a genuine effort to keep the information accurate, but public holiday dates, timezone rules and daylight saving transitions change, and regional or optional holidays vary within a country.
Always confirm dates and times against an official source before booking travel, taking leave or scheduling anything that matters. PlatformOwn accepts no liability for decisions made on the basis of information shown here.
