"Pantang" for siblings to marry on the same year


New Member
Hello all!

My fiance's brother would like to hold his wedding ceremony on the same year as us. Heard from the Aunties that this is a "Pantang" gesture; Suggest to marry 1 year apart.

Whats the definition of 1 year apart?
1) 12 months apart
2) after chinese new year
3) FY21 vs FY 22

Any advice or views on this?
