A monthly pass is valid for a month (calendar dates), meaning it lasts for a month regardless of the number of days during that period. For eg :
- if you purchase a monthly pass on 3rd Jan 2020, it will expire on 2nd Feb 2020.
- if you purchase a monthly pass on 4th Feb 2020, it will expire on 3rd Mar 2020.
The same rule applies for the Yearly Pass as well, which lasts for a year.
