回答1:
Mounts are starting from 0 to count. Type just;
val month = c.get(Calendar.MONTH) + 1
回答2:
Mounts are counted from zero (like array index):
- January = 0
- February = 1
- ....
If you make an array that contains mount names in correct order the mount number given from calendar is the index of this array.
You can add one to it to get real mount.
