Weekends
Weekend hashpoints seem to be OK but the testing has not been too thorough yet.
30 West
If the grid of hashpoints overlaps the 30W line, the ones on the same side as the centre point are correctly calculated. The remaining points use the wrong date. This should not be hard to fix but might take a little time. --Sourcerer (talk) 15:39, 20 January 2016 (EST)
Dates before 2008-05-27
Points before Tuesday, May 27, 2008 might not be correct. --Sourcerer (talk) 15:42, 20 January 2016 (EST)
