Check this page on the RBI website. In the table present on that page, there is a column which is called Commencement of premature redemption which lists the interest payment dates (as the Early exit option after 5 years can only be done on the Interest payment date). Starting from Tranche 10, it lists interest payment dates that are different from the issuance date (which is also an interest payment date) hence sharing both interest payment dates for every tranche. For the second interest payment date for Tranches 1-9, we can get some of that information from the BSE website (like for example, second interest payment date Tranche 1 is May 30th as per BSE website). Some Tranches (aka 2-3) don’t have any information present about the second interest payment date on the BSE website and those dates I have derived based on estimates. Also, the actual interest payment dates will likely differ a bit if that date is a banking holiday or a non-working day. I have compiled the data from the RBI website and BSE website in the table below -
