不是的。 有 call schedule. cd 的明細裏麵有個表 JPM的每個月隻有一天可以call

JPM callable all are Par Call,  meaning when called, the FULL CD amount is called.

The date it can exercise to call is the date correspondent to maturity date.  For example if the CD matures on 09/27, on the 7th month of the CD, it can call on the 27th of that month, so on so forth.

The call schedule of each callable CD will tell you that.  Each bank's different.
