The look is clean, simple, easy to use. It offers separate Calendar and Upcoming Events widgets. (Please, all calendar developers - make an Upcoming Events widget!) It is missing only TWO - please note developer - only TWO features to make it perfect.
(1) Although it has begin- and end-date data fields, it does not have end-time data field.
(2) It ONLY has a 24-hour time field, which is fine for Europe, but not for civilian use in the USA. Since my default time setting in WordPress is to show a.m. and p.m., my Wednesday night choir rehearsal shows 5:45 a.m. (horrified singers) or 17:45 p.m. (with 24-hour time, a.m. and p.m. are obviously not necessary).
