Can I Gift 1 month of game time in WoW?

I'm curious, is it possible to gift a month of game time in World of Warcraft (WoW) to someone else? I've been looking into different ways to surprise a friend who enjoys playing the game, and this seems like a great option. However, I'm not sure if the game allows for such a gift, and if so, how I would go about doing it. Could you please clarify if this is an option, and if so, provide some steps or instructions on how to make it happen? Thank you in advance for your help!
