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.
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.
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!
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.
A: No. The Bitcoin Calendar is an independent, community-driven initiative with no affiliation to Bitcoin core developers, companies, or foundations.
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.
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.
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.
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.
A: Yes. The Bitcoin Calendar is fully responsive and (mostly😅) optimized for mobile, tablet, and desktop viewing.
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.
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🔮.
A: Events are sourced from reputable archives, academic papers, news reports, and primary documents. Each event page includes citations or references where possible.
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.
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.
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.
