It shouldn't come as a surprise to see WWE's biggest PPV of the summer to be in August. It is, however, interesting to note that August 21st falls on a Saturday.
SummerSlams first started out as a Monday night event for its early years dating back to 1988. However, the PPVs were moved to Sunday nights in 1993 - likely due to '93 being the year that Monday Night Raw first started - and have remained that way until this year.
Even though people are going to report that this will be the first SummerSlam to take place on a Saturday, it technically isn't true.
Emphasis on the word 'technically'.
1992's edition of the event took place from Wembley Stadium in London on Saturday August 29th. It aired on PPV the following Monday to keep with its then tradition.
Las Vegas' Allegiant Stadium is the rumoured venue for this year's show.
This is also noteworthy because there is a Manny Pacquiao fight being hosted in the same city on that very night.
