[BUG] Date distance between children appears to be sometimes incorrectly calculated #329

Open brianfreud opened 9 months ago

brianfreud commented 9 months ago

Version Number problem appears in 10.0.0.0-beta8

Describe the bug See the attached gedcom. Two of the children here are somehow being miscalculated, though the other 3500 people in the same database are not having issues.

Children of Justus Wilhelm Schweitzer and Barbara Elisabeth Dehnhardt: Peter Schweitzer b. 26 Jun 1875 Peter Schweitzer b. 1 Mar 1876 Wilhelm Schweitzer b. 3 Jan 1877 Velten Schweitzer b. 3 Jan 1877

To Reproduce Steps to reproduce the behavior: Load the attached gedcom. Take a look at data errors.

Expected behavior Between the two Peters is 249 days, or 8.3 months. FTA is flagging this as an "born too soon after sibling" error; at best a note about a possibly slightly premature birth should be raised.

Then, between the second Peter and the twins I calculate 308 days. FTA is calculating it as only 151 days. It's also oddly flagging the possible error only for Velten, but not also for Wilhelm. 2024-02-26.ged.zip
