Why do calendars show different Ekadashi dates?
Three reasons, and all of them are legitimate.
1. Location
Ekadashi follows your local sunrise. Delhi and Los Angeles fall on different days for 56% of Ekadashis; Delhi and New York for 41%.

Sometimes a tithi covers two sunrises, and sometimes none at all. Traditions resolve these differently.
