Bug ID: 329285
Summary: Date for the holiday Ascension is incorrect.
Classification: Unclassified

Version: unspecified

The Ascension is celebrated on the 40th day of Easter. This is counting from
Easter itself as the first day of Easter. Thus, the holiday is celebrated on
the 39th day after Easter, not the 40th day after like it currently gives. It
should be on a Thursday, not a Friday.

On a similar note, "Trinity" (assuming it refers to Trinity Sunday), should be
on the Sunday after Pentecost, not some random Thursday right before it.

Reproducible: Always

Steps to Reproduce:
1. Pull up any calendar region with the Ascension and Trinity included. I'm
getting this problem in the United States calendar.
2. Go to May 2013.
Actual Results:
Ascension is on May 10th, Trinity is on May 16th.

Expected Results:
Ascension should be on May 9th, Trinity should be on May 26th
