It was fine.
Today is my dead father's 90th birthday.
It's been 10 years since I celebrated his birthday last.
January 15 is known as koshogatsu (小正月), literally means small new year. It is the first fullmoon of the new year in luner calendar. The customs remain after changing to the Gregorian calendar. There are some events such as burning new year's decoration but I do not do anything special by myself.
There was a progress at work.
At night I watched a recorded lecture for visiting Ise.
I started preparing the 153rd ebook.
