# Calculation of events duration time at for a specific period

Hi Everyone,
I've this code that able to create a xlsx file that holds the electricity tariffs over a year, depends on the hour and the season, it called Time of use,
I am interested to calculate the duration time (in hours) over one year, for every tariff, and save this data in the same table (or another table it's fine too).
for example : Tariff 0.2307 was active for 2000 Hours...etc.
%% Define date&time arrays :
t1 = datetime(2021,1,1,0,0,0);
t2 = datetime(2021,12,31,23,0,0);
dt = (t1:hours(1):t2)'
%holidyas date array
Holidays = [datetime(2021,3,27,0,0,0) datetime(2021,3,28,0,0,0) datetime(2021,4,2,0,0,0) datetime(2021,4,3,0,0,0) datetime(2021,4,14,0,0,0) datetime(2021,4,15,0,0,0) datetime(2021,5,16,0,0,0) datetime(2021,5,17,0,0,0) datetime(2021,9,6,0,0,0) datetime(2021,9,7,0,0,0) datetime(2021,9,15,0,0,0) datetime(2021,9,16,0,0,0) datetime(2021,9,20,0,0,0) datetime(2021,9,27,0,0,0)]
Holidays = Holidays'
DateNtime=zeros(numel(dt),2); %preallocating

It's not clear how you want to calculate these values.
Assuming you want to find the first and last timestamp for each tariff and take the difference, you could use groupsummary and then take the difference.
t = 8760×2 table
