Wow! I thought some of the people I work with were long term planners. You win!
As Zac said about the start and finish times, but the time does matter if you plan on counting those peaks for AMC recognition (winter 4K list). Cannot start a hike before the 4:48 UTC time on Dec. 22, and must be off the trail buy the corresponding time of the spring equinox.
It's good to hear from you, albeit indirectly and nice job spelling my name correctly. My friends and family still struggle with it.
Ken is 100% correct and thank you for the clarification. Those are indeed the AMC winter rules. Still, some people aren't too concerned with the start and end times as opposed to dates. As my good friend Steve says, "You only have to satisfy yourself".
That being said, a lot of us here, myself included, are "purists" in that respect and do adhere to those rules.
Don't forget to enjoy summer and fall on your way into winter
