At the time of Sandy's death, it is obviously Christmastime (Heather asking about decorating the tree/Christmas music playing in scene just before Sandy's seizure; Christmas decorations present after Sandy's death during dinner scene with Janine, Peter and his partner discussing Janine's rights with Heather.) When Janine reads Sandy's obituary, a brief shot of the clipping states Sandy's death date as Friday, June 29, 2000 (which was actually a Thursday.)
