 Hello,

I would like to report an issue that may or may not already be known, but that has been a bug that has prevented our project from progressing to more recent releases of pandas. We are working with datasets that extend out past the maximum timestamp date of 2262-04-11, so we generally use period ranges rather than datetime ranges. However, starting with release 1.1.0, the resample functionality no longer works with period ranges that extend past 2262-04-11. The screenshots below show an example of this phenomenon. Would it be possible to restore the resampling functionality for period ranges that extend past 2262-04-11 in future releases?

Example Code Snippet: import pandas as ps from datetime import datetime print(ps.__version__) rng = ps.period_range(datetime(2000, 1, 1, 0, 0), datetime(2300, 1, 1, 0, 0), freq="1D") df = ps.DataFrame(index = rng, data = [i+1 for i in range(0,len(rng))]) resample_df = df.resample("6H").interpolate() print(resample_df.head(10))

Result when running with pandas==1.0.5: <image004.png>

Result when running with pandas==1.1.1: <image003.png>
