Final answer:
The elapsed days in a year can be determined using Calendar functions in programming languages like MATLAB.
Step-by-step explanation:
The elapsed days in a year for specific dates can be determined using Calendar functions. Calendar functions in programming languages like MATLAB allow you to perform various operations related to dates and time, including calculating elapsed days.
Here is an example using MATLAB:
Use the datetime function to create a datetime object for the specific date.
Use the yday function to get the day of the year for that datetime object.
By subtracting the day of the year for the starting date from the day of the year for the ending date, you can determine the elapsed days in a year between those dates.
