Most dudes use Google calendar as the application only on the phone, which, I think, is not good. Recently got a wall calendar and thought what to do with him, he’s still not as convenient as the app on the phone. But this calendar is so gorgeous that words cannot explain. He’s great. Perpetual calendar will keep track of your appointments or a time when you have to go to the doctor, but it will look damn good on your Desk. Each calendar is printed under the order of typesetting letters. You choose any suitable for you style, design, accord with dudes and they print you a harsh cool thing. Then the calendar delivered to you, you collect it and it is beautiful. The cost of such things from $ 50.
