The Sun squares Saturn at 28 degrees of Scorpio-Leo, becoming exact at 7:40 P.M., EST August 21, but this energy will be apparent the day before.
Sun-Saturn transits can seem limiting and restrictive, and you may feel tired or without enthusiasm.
The best course of action is to go about your business and if you can accomplish that you will have done well. Limit expectations for this day, and know this energy will pass quickly, and it's best not to take it too seriously or get too gloomy.
If you have fixed planets (Leo, Scorpio, Taurus, Aquarius) at 25-27 degrees this may set off something in your chart, and can seem more negative.
This will pass quickly and by next Wednesday the Sun will conjunct Jupiter bringing a more optimistic period.
This energy will play out in the world as negative news and destructive events. This transit will occur every year, several times.
