That summary is irrelevant for the calendar badge. You are summing the number of days you have logged caches on. The calendar badge sums, as can be seen in my original response, the number of dates in the calendar that you have logged a cache (plus 366x the number of completed loops).
This means that the badge first has a value from 0-366, until you have filled your entire calendar.
After that, the number will be between 366 and 2x366 until you have filled your calendar twice. However, you don't get one more for each day you cache the second year, you only get one more for each date where you only had one find previously. However, for each date that you logged more than one cache on while filling your first loop, the count will already be incremented.
