New to me, although maybe it shouldn’t be. Old Christmas is a relic of the Julian calendar, celebrated in rural parts of West Virginia until relatively recently on January 6th. From West Virginia Public Broadcasting:

In the late 1500s, Pope Gregory XIII changed the calendar to match the solar cycle more closely. To do so, the Julian Calendar had to be reduced from 376 to 365 days, eliminating 11 full days. Some countries, though, resisted the change and kept the old Julian Calendar. It took nearly 200 years for England and Scotland to come around. Both countries adopted the Gregorian Calendar in 1752.

About this time, many of these English and Scots were emigrating to the Americas and settling in Appalachia. Some didn’t know about the change or refused to adopt the new Gregorian Calendar and kept the extra 11 days in their calendars. This meant that for them, Christmas fell on January 6 rather than December 25.

As of 2020, the average undergraduate GPA at Harvard is 2020. From Aden Barton in The Crimson via Orin Kerr.

“If grade inflation continues at its 2021-2022 pace, for example, the average GPA of the Class of 2028 would be over 4.0.”

Sesame will soon be required to be labeled as an allergen on food, which is leading to more sesame being used in food.

Food industry experts said the requirements are so stringent that many manufacturers, especially bakers, find it simpler and less expensive to add sesame to a product — and to label it — than to try to keep it away from other foods or equipment with sesame.

As a result, several companies — including national restaurant chains like Olive Garden, Wendy’s and Chick-fil-A and bread makers that stock grocery shelves and serve schools — are adding sesame to products that didn’t have it before. While the practice is legal, consumers and advocates say it violates the spirit of the law aimed at making foods safer for people with allergies.

“It was really exciting as a policy advocate and a mom to get these labels,” said Naomi Seiler, a consultant with the Asthma and Allergy Foundation of America whose 9-year-old daughter, Zoe, is allergic to sesame. “Instead, companies are intentionally adding the allergen to food.”
