Got The Time Most Of The Time
(I am on vacation in Mexico, hanging out with some fellow campers. I have been at this particular spot for a couple months longer than them, and have gotten used to its natural cycles.)
Camper #1: “Oh, hey, what time is it?”
Me: “It’s…” *I look at the sky, hold up an arm, and judge the distance between it and one of the constellations.* “…about 10 o’clock.”
Camper #2: “I’m going to check that, and if you’re right, that’s awesome.” *looks at his cellphone* “It’s 10:07! Wicked!”
(Over time, I got less accurate, since the position of stars change throughout the year, but my estimates were still within an hour of the actual time.)
