What is a Millisecond?
The millisecond is one thousandth of a second — imperceptible to humans but critical in electronics, networking, and high-speed photography. Human reaction time is typically 150–300 milliseconds. Internet latency (ping) is measured in milliseconds; 20 ms is considered excellent for online gaming. Modern processors execute hundreds of millions of instructions per millisecond.
What is a Day?
The day equals exactly 86,400 seconds and corresponds to one mean solar day — one rotation of the Earth relative to the Sun. The solar day varies slightly throughout the year; the 86,400-second definition is an average. Days are the most intuitive time unit for human planning: work schedules, deadlines, and calendars are all structured around days. There are 365 days in a common year and 366 in a leap year.
