The current Japanese translations for date filter operators are a little bit confusing. Probably most Japanese users agree with this. This is because the translated sentence is too long. Here are some examples.

|. label |. en |_. current ja translation|
| label_in_less_than | in less than | 今日から○日後以前 (earlier than or equal to n days from today) |
| label_in | in | 今日から○日後 (n days later from today) |

The attached patch changes those translations simpler and more clear. Samples of the new translation as follows.

|. label |. en |_. new ja translation |
| label_in_less_than | in less than | n日後以前 (before n days) |
| label_in | in | n日後 (n days later) |
