I've done it!
Since I had some #Covid-related downtime, I've been teaching myself to program, and I've finally managed to implement #Python functions to compute the time of #sunrise and #sunset according to traditional #Indian methods.
Admittedly, I don't think my method is the same as the one described in the #SuryaSiddhanta, but the translation and commentary I was able to find are really vague and unclear about what to actually do. Mine at least is consistent with what was known at the time
