As for the fiscal year is concerned many countries, including Japan does not follow European or North American calendar and in Japan the fiscal year ends March 31 and Start April 1 (

The first day of April has broad significance in Japan. It marks the beginning of the government's fiscal year. Many corporations follow suit. In addition, corporations often form or merge on that date. In recent years, municipalities have preferred it for mergers. On this date, many new employees begin their jobs, and it is the start of many real-estate leases. The school year begins on April 1. I am not worried when your fiscal year ends. I was worried that March 31 would come and go with no results and I would get an email from support saying 'well that happened last fiscal year, so we can't change anything.' Or that you were trying to cook the books for whatever reason... Or that this had happened to many other users who hadn't realized that you were wrong and just said 'okay here is another $1,000 to take care of my zero balance.' I hope you haven't incorrectly reversed double transactions to any of your other users...
