Doubt - Range of values for Dates

[Shantanu]

The range of values for dates in the lecture is mentioned as 0,1,2...365

I understand that how it will be working when it starts from zero eg. print(31) will be 1st Feb.

But why is it starting from zero in the first place as the dates always start from 1, so shouldn't the range for dates be 1,2,3....365 ?

[Aman Kumar]

It's totally fine, I guess to start from 1 as well. There has been a general notation of initializing the value of a variable from 0, this might also be the case here. However one is free to use from 1 also, I guess.

Thanks again Aman.

In the real world, counting or sequencing always starts from 1.

But in computers, counting or sequencing starts from 0 because it is a binary number system.

Hence, we always start from 0 instead of 1.
