Crickets cannot tell time

... but they can tell the temperature. According to the Farmer's Almanac:

To convert cricket chirps to degrees Fahrenheit, count the number of chirps in 14 seconds, then add 40 to get the temperature.  

Example: 30 chirps + 40 = 70° F 

This was verified by

Dr. Peggy LeMone of The GLOBE Program (a science education program funded by NASA, NOAA, NSF, and others). . . .

However, she concluded that temperature was more accurately measured by chirp counts at 13 seconds plus 40.

The ones who cannot tell neither the time nor the temperature end up here.
