[Star Wars] How long did it take for Palpatine to personally call every clone trooper commander about Order 66? How did the Jedi not catch on while the calls were being made?

We see the calls are personal. He starts off with "Commander Cody" on the first call we see. In addition, each time we see the hologram he has a different inflection in his voice. 

Nobody else knew about Order 66, and only he could issue it. There were about 10,000 Jedi and assuming each call took 30 seconds, that's 3 and a half days of straight calling to each clone unit. 

How did the Jedi not catch on to that? "Hey wow in the last two days half the Jedi were killed by their clones weird huh". 

Like Yoda could feel they were being killed, could no one else? Or was he the last one to be killed?

About 100 Jedi survived, you're telling me 9900 Jedi were killed over three days and NOBODY NOTICED? For crying out loud I could notice that and I'm drunk. Actually I'm drinking as I type this so I apologize if this is becoming nonsensical. 

TL:DR Why could the Jedi not notice all their friends getting killed over the course of three and a half days? Or how long did Palps actually take to personally call each Clone Commander and tell them to do the deed?

It's likely he sent individual messages to the Clone Commanders accompanying members of the Jedi Council, as they would be the main priority. After that order went out, he sent out a more generic message to the Army commanders who then filtered the order down the chain.
