A location's weather is never continuous. It may change once a day or even once an hour. For example, in some places, it may be sunny in the morning but cloudy in the evening.
A minimum-maximum thermometer is used to measure the minimum and maximum temperatures of the day, which are always included in a location's weather report. The morning hours are when the lowest temperature is felt, and the afternoon hours are when the highest temperature is felt.

Birds follow the light of the stars at night, and the light of the sun during the day. A Siberian crane travels from Siberia to India once a year.
