You can follow the instructions in your owner's manual or change it every 50,000 miles.
According to Honda, 105k miles. The maintenance schedule is at the link below. http://techinfo.honda.com/rjanisis/pubs/OM/OD0101/OD0101O00236A.pdf
Most often this requires a battery change. However, it may also be caused by wiring problems.
There is no magic number as to how often you should change your brakes. Brakes will wear down differently depending on the make of the brake and they will start squeaking so you know that you need to change it.
How often brakes should be changed depends on the type of brakes in the vehicle and the use of the bakes in the vehicle. However, the general rule is every 10,000 miles.
i depends on what kind of city you live in. when you live in tropic country and it surely very dusty may be you should change the filter for every 2 regular service AC maintenance. IIMHO

Honda recommends @ 45k miles and then every 30k miles after that.
The factory recommended mileage/time interval for replacing the timing belts on the Honda Odyssey is 10 years or 105,000-miles, whichever comes first. That being said the type of driving, environment, how often the engine was run, and so on can create conditions where a much earlier interval is advisable. The price of preemptive replacement outweighs the potential risks from belt failure and tension degradation in this application.
Every 12 months.
15000 miles
Every 100,000 miles
