A small but growing community on GitHub and Hindu dharma forums is working on open-source annual Tithi calculators with portable builds. Examples include Panchanga-Portable and JyotishTools. The advantage of open source is transparency: users can inspect the exact formula for sunrise, Tithi duration, and sandhi (junction) periods.
