How to calculate 14 days out of malaysia ?

Dear All,

I  started working in Malaysia Penang from April 2018.

I planned to go to india for personal trip on coming September month. I have confusion on calculating the 14 days out of malaysia for resident tax calculation

I will depart date on  5th September 9PM from KL
Return on 19th September 8AM  to KL

1.Should I include 5th & 19th on 14 days calculation ?  OR
2.Should I consider only depart date & not return date

please correct me if am wrong.

Here is my calculation
5th Sep - 1 Day (start from KL - 8PM )
6,7,8,9,10,11,12,13,14,15,16,17 ,18 - 13 Days
19th Sep - 1 Day (reach KL  8AM).

if I return on 19th Sep 8AM will be consider as total 15 days  or 14 days ?
Or Should I reach 13th sep itself ?

I already booked the tickets for 18 days But going to change the dates.

Eagerly waiting for your responses.

Regards,
Jagan
