Most people define mid-morning time as the hour between 9 and 10 a.m. Depending on the season, mid-morning is generally understood to be the interval between dawn and noon. However, with regard to the workday, which can start at 8 a.m. regardless of the season, the time between 9 and 10 a.m. serves as a generally steady and predictable period for mid-morning to occur. Depending on their schedules, these mid-morning hours may also correspond with when people arrive at work.
It can be useful to consider what morning is in order to respond to the question “What is mid-morning?” Morning is defined by Merriam-Webster as “the period from dawn to noon or…from the beginning of the usual time of daily activity to noon,” while mid-morning is defined as “the middle of the period from sunrise to noon.”
For scheduling purposes, it may be simpler to conceive about mid-morning in the context of the second part of the definition: “from the beginning of the typical time of daily activities to noon,” because the time of sunrise can vary significantly depending on the season. Regardless of the season, a lot of individuals awaken about 6 a.m. to begin getting ready for work at 8 or 9 a.m. It makes sense for mid-morning to occur around 9 a.m. since it is exactly halfway between noon and 6 a.m., the starting and ending points of morning.
