As answered by people managing Vim and Day-Number.
Day-Number's answer:
Day-Number automatically detects your timezone and location, then displays ISO 8601-compliant day numbers, week numbers, and country-specific holidays - all in one place. Unlike basic calendar tools, we combine real-time timezone intelligence with international holiday support and powerful date calculators in a clean, modern interface.
Day-Number's answer:
We automatically detect your location and adjust everything for you - perfect for travelers and remote workers. We provide accurate ISO week numbers (which many tools get wrong), support multiple date format standards, show upcoming holidays for your country, and include powerful date calculators. Everything is free, privacy-focused, and works beautifully across all devices.
Day-Number's answer:
Remote workers and digital nomads managing multiple timezones, developers and project managers who work with ISO date standards, international teams coordinating across different countries, and anyone who needs quick access to standardized date information without complex calendar apps.
Day-Number's answer:
As developers working with international teams, we constantly needed to answer "What's today's ISO week number?" or "How many days until the deadline?" Existing tools either lacked timezone intelligence or showed incorrect ISO calculations. We built Day-Number as the tool we wished existed - one that instantly shows where you are in time, no matter where you are in the world.
Day-Number's answer:
Next.js 15 with React 19 and TypeScript for performance and maintainability, Tailwind CSS for responsive design, date-fns-tz for precise timezone calculations, and next-intl for internationalization. We use ipapi.co for geolocation and Nager.Date for holiday data, deployed on Vercel's edge network for global availability.
Day-Number's answer:
As a free public tool, we serve thousands of individual users rather than traditional customers - including developers relying on accurate ISO standards, international businesses managing multi-timezone operations, and remote-first companies. We're adopted particularly in tech hubs across North America, Europe, and Asia, especially among digital nomad communities.

Lua is quite small, encouraging distros to include it. The ubuntu gvim has, and the gvim AppImage linked from vim.org does. The default Makefile from github is set up to not include it, but you can uncomment one line there to get it. Source: over 3 years ago
I've not used vimwiki locally (tho I'm old enough to remember the Vim wiki on vim.org :), but I think what you are wanting to do is extend vimwiki's syntax file. I presume it installs one at $VIMRUNTIM/syntax or or ~/.vim/syntax. If... Source: almost 4 years ago
