20 15, it is best to buy funds before may 1 or after the may day holiday. Similarly, it is the same when we meet a long holiday in June, such as 65438+ 10 1. The reason for this is the following：

Generally, banks do not handle it outside 9: 30- 15: 00 on the normal trading day, but online banking is possible (24-hour trading mode, almost every bank has the service of online banking to buy funds, which can be operated after opening an account), but applications submitted outside trading hours are counted as the next trading day, which means that fund applications need a certain period of time to be reviewed and can enjoy holiday interest after reasonable arrangements.

In short, holidays similar to the above problems can be handled in this way.
