About 80 days.
Not to hijack this thread and solely to prove a point, take for example my startup weekend project. Just this weekend (Saturday and Sunday 9AM-9PM) I built CarePrice which utilizes geolocation, a backend api, user management system and authentication, frontend, accompanying social networking, additional pages, and the full gamut. Albeit I did have a little help, I'd attribute 90% of the development work to myself on this one.
It's this ease of development you can look forward to with more experience under your belt! Keep on hacking and the days just start to shave off.
