How long would it take to get to 80?

Hello GW2 players. I started my Charr warrior yesterday at around 1 P.M and today at 1 P.M I got him to 15. I haven't done any crafting skills either. So how long would it take?
Also, I only play on weekends, but I play all day on the weekends(7 in the morning to like midnight)
I was planning on waiting until Lv.60 to do crafting so that I can do my 2 crafts and get to 80 like that. Or should I start crafting now?
Also, how much does each craft take to get to 400 money-wise?

Simply put: the more you focus on the leveling up, the less you will enjoy it.
Leveling in GW2 is fairly fast, but if your aim is to rush to level 80, you will most likely be disappointed with what you find at level 80. The best approach to this game is to enjoy every level, to make the most out of it, to explore as much as you can, and to enjoy your time playing through the lower level zones. Do dynamic events, renown hearts, skill challenges, jumping puzzles, and crafting... or whichever parts of that you like most.

So with regard to crafting: if you start crafting right away, then at least the items that you craft will be useful to you while you're leveling up. If you wait until level 60 before you start crafting, then crafting will feel more like a chore, and you'll be crafting a lot of useless items (items that you have no use for, and that you can't really sell either because nobody else is interested in them).

I'm not putting to much emphasis on the leveling. I love ravaging through enemies with my sword and axe. Loving the Blood Legion story too.
So I should start crafting now? If there's enough content later on I would need to rely on just the crafting to level?

Also, since I'm a warrior, armorsmith and weaponsmith would be the best crafts right? Or should I do another? Like cooking?

There's plenty of content available at all levels to level up, so yeah, I do recommend to not wait too long with crafting.
It's entirely up to you which crafts you want to take... armorsmith and weaponsmith will ensure that you can create your own armor and weapons, but yeah, you could also choose cook (for a wide range of consumables that provide boosts at all levels), jewelcrafter (eg. rings, amulets and item upgrades). It's all up to you...
Do keep in mind that cooking is definitely the most expensive and the most space consuming of all crafts...

I'd advise not trying to do armorsmithing and weaponsmithing at the same time. They both use a lot of the same materials so you'll struggle to keep them both up unless you buy a lot from the trading post. I'd pick one of those two and do either jeweling or cooking for your last one. Artificing could also work but you'd really only use the potions from that.

Alright cool. Thanks. I'll do armorsmith and jewel. Later on I'll do cooking if I need to. Thanks for the help. :)

Personally I do crafted when I feel stuck(ish) - Like after completing two starting areas, going into the next tier of maps for recommended levels. I'm usually maybe level 15 or 16 by then. My traits aren't starting to shine and character development isn't quite there yet as far as skills go. That's when I usually craft 5 to 10 levels.

I'd suggest not waiting 'til the last 20 levels to craft if you have the resources to do it sooner. Between 65 to 80 there are 3 or 4 good maps for experience as well as resources so you can start saving money towards level 80 gear (rare armor, exotic weapon - then either buy exotic armor or do dungeons to basically get it free).

As for time, my first character took a very long time, though I don't have an /age number for you. That was a ranger. My 2nd character to 80 was much much faster (mesmer) due to superior PVE abilities and better gear thanks to a higher starting bank amount.

My current character is a 58 thief with an /age of 41 hours. 10 of those levels was mastering leather crafting. Through just PVE and map completions I'll get my thief to 80 in another 10 to 15 hours of play.

There's a lot I want to do at level 80, and I already took the slow scenic route with my ranger. So I don't mind rushing. You asked, so I figured I'd give an example.

If you play any content (as opposed to standing around in already discovered areas and just talk to people) you can expect to spent a maximum of 1.5 hours per level (regardless of which level you are playing).

I usually try to complete the daily achievement (which gives a nice xp boost) and if I still need some levels to catch up with my personal story I try to explore regions I haven't already explored.

Also, do yourself a favor and explore each of the cities completely. It's not hard to do but you'll get nice exploration xp.

My mentality at launch was to get to 80 quick via crafting/story quests and questing around the zones. I had the 3 day head start was level 80 within 2 weeks.
