MATCH D:
The spreadsheet shows a bolded and bordered block of 2-3hrs for each match that is the suggested overlap.
Here is a zoomed-in snapshot, showing the overlapping time for your group of 4. UTC time is on the top, WGT time in blue on the next row:
MATCH D :: BigKnight & DaveDwingdale vs emmalinks & Corwyn
D :: Your group can only play on a weekday. Please schedule for Mon 1/26, Wed 1/28, Thu 1/29 or Fri 1/30, in the best overlapping block of time, between 5:30pm-7:30pm UTC (9:30am-11:30am WGT time).
The notes for Corwyn show his 9am block really starts at 9:30am, hence this match should start half an hour later than on the grid. (Sadly, the spreadsheet formulas don't work with half hours!)
BigKnight & Dave (DaveDwingdale ): your 12:30pm local time.
Emma (emmalinks): your 6:30pm local time.
Corwyn: your 9:30am local time.
