Calendar

The calendar below is a Gregorian calendar with mostly Julian dates.  Unless otherwise stated, the general rule is that if the date is from a Russian document, or marks an event that occurred in the Russian Empire before January 31, 1918, it uses the Julian calendar.  Dual dates may be added over time.
