i learn something new today.

my PC google calender, i got subscribe to malaysia holiday calender.
so basically, if got any holiday due to festival or agong birthday, will appear in my google calender in another color.

but it doesn show on my android google calender.
i just figured out how to make it show. after an hour of google.
lots of people having this issue as well.

the answer is abit weird. just download any 3rd party calender app.
for example "business calender free" from play shop.

launch and choose which calender from your gmail acount to show.
after than can delete the app.

go back ori google calender, choose calender, will have new option malaysia holiday for selection :-)

weird fix, but it works. :-)
