set value of a variable according to date

I have a table

date                          seasons
----------------------------------------
01-January-2020 
02-January-2020

This date is "datetime" variable. I want to set the value of "seasons" like

if 01-March-2020 < date < 31-May-2020
    seasons = (the value of the cell at the time of O1-March-2020)
end

I would like to understand how to write if conditions for datetime variable.

I see https://www.mathworks.com/help/matlab/matlab_prog/compare-dates-and-time.html to set up the order on datetime variables.

But I still do not see how I can refer to the value of the cell at the time of 01-March-2020

Thank you in advance.

hello

you have to convert to "numerical" date format using datenum

so your code would be now :

d1 = datenum('01-March-2020');
d2 = datenum('31-May-2020');
if d1 < datenum(date) < d2
    seasons = 'spring'
end

Thank you.

d1 < datenum(date) < d2

This will not do what you think it does. Read the warning mlint is giving you.

No need to convert to a numerical date:

d1 = datetime('01-March-2020');
d2 = datetime('31-May-2020');
date=datetime('10-March-2020');
if d1 < date && date < d2
    seasons = 'spring'
end

seasons = 'spring'
