Bitcoin Calendar – Frequently Asked Questions

1. About the Project

Q: What is Bitcoin Calendar?

A: Bitcoin Calendar is a curated, chronological archive of milestones in Bitcoin history, free and open-source software (FOSS), cryptography, and economics. It spans from early cryptographic breakthroughs like the Enigma machine to landmark Bitcoin events such as Bitcoin Pizza Day. The goal is to preserve and connect the key moments that shaped digital currency and freedom tech.

Q: Why does the calendar include economics, FOSS and cryptography events alongside Bitcoin milestones?

A: Bitcoin’s creation was built on decades of innovation in cryptography and open-source software as well as the ideas in Austrian Economics and libertarianism. By including events like the depegging of the U.S. dollar from gold, David Chaum’s launch of eCash or the release of PGP encryption, the calendar shows the full lineage of events, ideas and technologies that shaped Bitcoin.

Q: Who created this project and what’s its mission?

A: Bitcoin Calendar is pretty much a one-man-army project, independently developed and maintained by Tony. Its mission is to provide a verifiable, accessible, and multilingual historical record that educates, inspires, and preserves the cultural and technical heritage of Bitcoin and related fields. I am eternally thankful to everyone who contributed to project development – be it a few sats, design tips or pull requests! Please keep 'em coming!

Q: How far back does the timeline go?

A: The timeline begins with Ludwig von Mises's birthday in 1881 and extends to present-day Bitcoin developments. It’s continuously updated as new milestones occur.

Q: Is this an official Bitcoin project?

A: No. The Bitcoin Calendar is an independent, community-driven initiative with no affiliation to Bitcoin core developers, companies, or foundations.


2. Using the Calendar

Q: How do I browse historical Bitcoin events by date?

A: You can view events using the interactive calendar or jump to a specific date using the navigation bar. Each event card links to a dedicated page with more details, sources, and related events.

Q: Can I filter events by category (Bitcoin, FOSS, cryptography)?

A: Yes. Use the category filters to view only Bitcoin Milestones, Archives, Fundamental Articles or Bitcoin Obituaries — or combine them for a broader historical view. Click a dedicated filter button in the header to browse available categories.

Q: How often is the calendar updated?

A: New events are added regularly, with both historical entries and recent developments. Updates are based on verified sources and streamlining community submissions is on the roadmap.

Q: Can I search for a specific event or year?

A: Absolutely. The search bar supports full text search, meaning you can find events by keyword, person, project, date or year. Search also allows you to paste a direct link to any event to instantly open it.

Q: Does the site work on mobile devices?

A: Yes. The Bitcoin Calendar is fully responsive and (mostly😅) optimized for mobile, tablet, and desktop viewing.

Q: Is there an app?

A: Yes. Bitcoin Calendar is available as a Progressive Web App (PWA) for iOS, Android, and desktop. You can install it by opening the site in Safari (iOS) or Chrome (Android/desktop) and selecting Add to Home Screen or Install.


3. Historical Context

Q: Why is it important to track Bitcoin’s history?

A: Understanding Bitcoin’s history helps contextualize its technology, culture, and economic impact. It also preserves the contributions of developers, activists, and communities who shaped the ecosystem. Some argue that this may help one predict Bitcoin's future🔮.

Q: What sources do you use to verify events?

A: Events are sourced from reputable archives, academic papers, news reports, and primary documents. Each event page includes citations or references where possible.

Q: How do you decide which milestones to feature?

A: Selection is based on historical significance, verifiable sources, and relevance to Bitcoin, FOSS, cryptography, or economics. The aim is to balance technical breakthroughs with cultural and economic moments.

Q: Do you include wider cryptocurrency industry milestones? 

A: Generally, no — the Bitcoin Calendar focuses on Bitcoin, free and open-source software, and cryptography. We deliberately avoid promoting the broader “crypto” industry, which often conflicts with Bitcoin’s principles of true decentralization and sound money. However, when a non-Bitcoin event has had a direct and significant impact on Bitcoin or the concept of “freedom money” — for example, the collapse of FTX or the Terra/Luna fraud — we include it. These entries serve as historical warnings, helping readers understand the risks of shitcoin casinos, centralized exchange failures and the importance of Bitcoin’s unique properties.


4. Contributing & Contact

Q: Can I suggest a new event for the calendar?

A: Yes. While event submission form is still under development, you are welcome to DM Bitcoin Calendar or Tony on Nostr to propose an event. Please include a date, description, and credible sources.

Q: How do I report an error or request a correction?

A: Contact us via Nostr or email, or open a pull request on GitHub. Corrections are reviewed promptly and updated after verification.

Q: Is the data open-source? Can I use it in my own project?

A: Yes. The Bitcoin Calendar’s data is released under an MIT license, allowing reuse with attribution. See our licensing page for details.

Q: Do you offer an API or data export?

A: An API and downloadable datasets are in development.

Q: How can I support the project?

A: You can contribute events, share the site, or support financially through Bitcoin donations. See details on a dedicated Support page. Every contribution helps preserve and expand the archive.
