xMacis can sort by years, months or days, but that many days overwhelms it. When sorting by month or year, it defaults to the last day of each month or calendar year, so daily resolution is not available.
With that said, if no more snow falls this month, the 120-month rolling total (February 1, 2016 to January 18, 2026) would be at 75.6" at DC if no additional snows fell this month. The current record is 92.8" ending every month from March 31, 2025 to November 30, 2025. DC would need 17.2" to avoid a new record by month end rolling. Probably the same for the daily unless some additional snows fell in 2016 between the snowmaggedon and the end of the month.
