Difference between Period().total_days() and Period().in_days() ?

Issue

I'm struggling to understand the difference between these two methods. I would expect them both to return the same result (90 days) but they don't.

Sample:

In [20]: import pendulum

In [21]: from_ = pendulum.parse('2023-01-12 17:49:49+00:00')

In [22]: to_ = pendulum.parse('2023-04-12 16:49:49+00:00')

In [23]: period = from_.diff(to_)

In [24]: period.in_days()
Out[24]: 90

In [25]: period.total_days()
Out[25]: 89.95833333333333

Someone else reported the same issue thing but it didn't clear up things for me.

I think that I got the answer by myself:

Given the previous time range, the correct duration in hours is 89 days and 23 hours. Therefore, I believe that

• total_days() calculates the total period duration in days.
• in_days(): finds the number of natural days present in the period, whether a day has 24 hours or not.
