183 Days / 183 MULTI Caches
The Challenge: Find a Multi Cache on 183 different days of the year, or 50 % of the calendar. They do not need to be consecutive and previous finds do count. Leap day does count.
Here is a challenge checker. It shows what days you still need to find a multi cache.

Did you know that of all active geocaches in the United States (over a million), only about 26,000 (less than 3%) are multi's? Per Project-GC, 2.55% of all U.S. caches are multi's as of the publication date of this challenge cache. From this perspective, even if you have well over 10,000 finds, you may only have ~300 multi finds but not on 300 separate days!
However, of all active geocaches in Germany (over 380,000), over 40,000 are multi's. This is well over 10% of all German caches!
When you log a find, please indicate on how many days you found a multi.
