One of the neat things about Holidailies is cruising the other entries, finding new people to read. Following one link after another here are a few fun things I found.
Find your age in Dog Years. That will put a spring in your step.
Find your Body/Mass Index. Or Don't.
Calculate the difference between dates. This is a useful tool for character ages. I can't tell you how much time I spend with a calculator figuring out who was born when, and by that I mean, I won't tell you.
Want to know how cold it really is? Use the Wind Chill Calculator.
See the current Phase of the Moon. In case it's too dark and cold to go outside and look.
For the screenwriter who is both math-challenged and structurally-confused, the Screenplay Beat Calculator. I remember back in the Dark Ages, scripts were 120 pages long and the Inciting Incident occurred on Page 17. I was reading an article last night that said the Inciting Incident should occur by Page 10. I predict, one of these days, we'll just put in on the Title Page. Under the Title. This is the story of what happened after this Inciting Incident occurred.
