Trending @Infosys; Promotion to JL4

Hi, as the quarter has already started (July-Sep) we didn't receive the promotion letters. But my manager is saying confidently and promised me that your promotion is started in April and you will definitely get in the July quarter.

Will promotion get any time during this quarter or only on the 1st day of the quarter?

Is there any option in infyme where we can see that our promotion is initiated or not?
