Ans.
Kashya month or skipped month is a rare phenomenon in Hindu calendar when complete lunar month is skipped.
According to www.drikpanchang.com calculations next Kashya month would occur in 2123 -2124 C.E. (none of us who is reading it would be alive to watch it) when Paush would be skipped.
Until 2123-2124 C.E. there would not be any Kashya month in Hindu calendar.
Last time when there was Kashya month in Hindu calendar was 1982-1983 C.E. when Magh was skipped.
In 2283-2284 C.E. our calculations predict another Kashya month when Magh would be skipped.
