Actually, it depends on which model year Accord it is. More recent accords (2001 on up) do not require the timing belt to be changed for at least 250,000 miles. They are durable and are made to last. Also, it depends on what kind of driving you do. Optically, if you have a 60% city 40% highway mix, 100,000 to 120,000 is the norm. If it's more highway driving, you may be able to go to the max of 250,000 miles.Older models may require changing the belt at 60,000 or sooner depending on how you drive it. Best to consult a honda technician that doesn't work at a dealership. Also, try vtec.net, it's the official non-company Honda website on the internet.Good surfing!
