What time does honor reset daily?

This typically takes place from 7 AM Eastern to 8 AM Eastern. Occasionally, Blizzard will have unannounced extensions to server maintenance, which could increase the amount of time between Honor resetting. Keep in mind that your honor adds up every week if you manage to get at least 15 honor kills.

Does honor reset every season?

Honor will not be reset at the beginning of Season 2. When Season 1 ends, there will be a two-week off-season period. When Season 2 begins, any remaining unspent Arena points will be converted to Honor Points at a rate of: 1 Arena Point = 10 Honor Points.
