Appeal period in hc

Dear Experts,

some tells 30 days and some tells 3 months to appeal in HC for divorce cases, which is correct?

I read hindu marriage act 1955 which says it is 30 days, please advise.

In my case judgement came on 8-2-17, immediately applied for certified copies and got judgement, decree and ordersheet on 2nd of March, as per the copies decree was release on 1st march. if it is 30 days should i consider march 8th or april 2nd?

Regards,

Srinivas
