Change Calendar 'working hours'
If you wish to change the 'working hours' in the calendar, adjust the following:
For 8am-5pm (default):
HKLM\Software\Microsoft\Calendar\ActiveTimes\Activ eTimes = 2210003E (DWORD hexadecimal)
HKLM\Software\Microsoft\Calendar\ActiveTimes\Activ eTimes = 2212003E (DWORD hexadecimal)
HKLM\Software\Microsoft\Calendar\ActiveTimes\Activ eTimes = 2C1C003E (DWORD hexadecimal)
Here's how this works.
The first 2 characters define the ending hour as a count of half hours since midnight, in hexadecimal. So for midnight, it would be 0 half hours in hexadecimal = 0. 5pm is 17 hours, or 34 half hours. 34 in hexadecimal is 22. 10pm is 22 hours, or 44 half hours. 44 in hexadecimal is 2C. You can use a calculator capable of hexadecimal conversions to get the hexadecimal number.
Similarly, the next 2 characters define the starting hour as a count of half hours since midnight, in hexadecimal. So for 8am.. 16 half hours, 16 in hexadecimal is 10. 9am = 18 half hours = 12. 14h = 28hh = 1C.
Using the above, you should be able to se the working hours to whatever you'd line.
Note that this value also adjusts the working DAYS. The examples here all use the default Mon-Fri workweek. See the "Change Calendar 'working days'" tweak to modify this.
Note that the ActiveTimes key and value may not exist. Simply create them first.
Note that you cannot set the End time earlier than the Start time, for obvious reasons
Note that you cannot set a Midnight end time. The best you can do is 11.30pm (2F)
