Open-source developer based in Türkiye. I build small, well-tested tools whose answers you can check.
lexdays: legal deadlines and business days you can verify. Every result lists each step and the statute or court decision behind it.
- Türkiye, US federal courts, England and Wales, the EU Court of Justice and Germany
- Calculation steps explained in 12 languages
- Adds the last day to your calendar, with reminders three days and one day before
- Python and TypeScript, checked against the same test vectors so both give the same answer
- MIT licensed, no dependencies
Live demo · Python package · npm package
- Rules and holiday calendars live in data files with their sources, not hidden in code.
- Where courts disagree, the tool shows the choice and its consequence instead of guessing.
- Dates outside the verified range raise an error rather than return a wrong day.
Questions, corrections and ideas are welcome in each project's issues.
