Buongiorno,
many events keep the same general dates as the proceeding year, and if they are on weekends then they stick to the same weekends.
The Italians - much to our continual amazement - are never big on updating public information until the last minute. However, we are already working on updating our Calendar of special
Christmas Events and Markets, so just keep checking back. We hope to find most of the updated information within the next week (or two

)
PS if you do find other sites with calendars - always check the dates. Sometimes they have the dates programmed in automatically, and they just change the year...but the DATE and DAY don't match. They are normally just trying to sell you hotel space so it is sooooo confusing.
Buon Viaggio,
Donna Denise.
