You’re in luck! It was a 5 minute job and can be done in isolation from the main templates. Copy the attached file (removed from its zip folder) to /modules_v3/GEDFact_assistant/_CENS/ to replace the existing file.
I have not included the 1825, 31, or 42 dates. The code as currently written will only work with a single day, not a range. Those can be added if you can settle on a date.
If you want to add those, open this file and you will see where they belong (around line 72). The format is pretty obvious, except that the year part of the date ‘value’ has to be one digit out because it counts from 0 not 1. So enter June, for example, as ‘5’ not ‘6’.
