I would think that for most guys with SO's the weekends are family time and more difficult to get away.

I'll set up a session with a young lady in the morning before I head to the tennis courts on a Saturday. I know guys play "Golf" in the weekends but they'll meet a young lady before they tee off..on the course after they've tee'd off on a young lady.
Speaking of golf, I once knew a young lady who booked a room at the golf course hotel. She was busy during the day, mostly on weekends. Guys just knew of her and where she incalled at.

I'm one of tose ladies. If you prefer mornings because it's a better time of day for you, that one thing. That being said, I'm at my best starting around 2:30-3pm. And I adore early evenings. At this stage of my life, 1-2 while "touring works for me.  

So, you don't always HAVE to book morning to be first, IMO.

I have a regular and I tend to do longer appointments. I make arrangements far out so it’s never been an issue.  

Your city's culture can play a big role in demand. For example, places like Vegas and Miami are party cities, so there may be more of a demand on the weekends. Whereas cities that are more known for business and conventions (like DC) are probably busier on weekdays.  

Another thing to consider is a lady's client base, even though you probably will not know what it is. As Holy stated, those with SO's and family obligations have a harder time breaking away on the weekends. Those who have more of a younger or single clientele may be busier on the weekends. I myself tend to be busier on weekdays and barely get requests on Sundays.  I am sure your ideology has a part in it as well.

The weekends have always been the slowest for us. It has been that way for a good many years.

Pretty much anytime during the day during the week is the busiest for me. I start at 9 am but will do earlier upon request.  I do not do late night nor do I cater to the drunk after bar time closes crowd, I am too old for dealing with that nonsense shit. Saturday is probably my slowest day, I think because guys are doing family time with the kids/grandkids. I do not have a select day off, it just really depends on which day that week I have no appointments.  
Guys are usually booking their "dental appointments" (code for getting their knobbin schlobbined) during the day during the week, so that is normally when my appointments occur.

Weekends probably work  best for single guys who work during the week ,guys who work weekends,providers who work a civic job during the week, and providers who are flexible to accommodate these time frame.

Depends on what the provider does and how may customers she can get.

For the longest time, I thought I was missing out on money because I couldn't work weekends. I was incredibly disappointed when I was able to take appointments outside of my normal hours. Everyone is with their family

for me at least.  I usually tour Sunday-Wednesday or Wednesday-Saturday depending on the city.  Some cities like Boston, I will stay longer than a week at times.  Sometimes the weekend days are busier than during the week and vise versa.
