If you record your exercise with an Apple Watch starting on the evening of a day, through the morning of the following day, the Monthly or Weekly Health App Summary will give credit for the exercise only on the day it ended with no credit for the day the exercise session began.
So let's say you start a workout late, such as 11:05pm, and finish at 12:05am. The Health app should record that you worked out for 55 minutes on the day you started, and 5 minutes on the day you ended. However, it will leave the day you started as blank and suggest that the workout was only for the day on which your workout ended.
As you can see, I walked on Sept 29, 2020 from 11:04pm-12:05am.
I closed all my circles! (actually for the whole month, with a workout every day for the whole month)
I worked out every day in September, however, because my workout finished at 12:05am, the Health app gives credit to the workout for the day the workout ended, with no credit at all for the day the exercise started. Ironically, the majority of the excerise was done on the day for which no credit was assumed by the Health App.
