Bug#930736: Summer solstice wrongly reported as spring equinox in the Russian calendar

[Oleg Kostyuchenko]

Package: bsdmainutils
Version: 11.1.2+b1

Hi,
Encountered the following /usr/bin/calendar output today:

$ LANG=ru_RU.UTF-8 calendar
# ... <snip>
Jun 20* Весеннее равноденствие

$ date
Wed 19 Jun 2019 03:49:39 PM MSK

"Весеннее равноденствие" = spring equinox. Expected is "Летнее солнцестояние" 
(summer solstice).

OS: Debian 10 (buster)

Thanks
