Date.Time Calculator vs Stadiametric Rangefinder

Date.Time Calculator lets you easily perform calculations involving dates, times, and time intervals, as well as convert between units of time — all with the familiar feel of a calculator. Date.Time Calculator supports the following operations: * Basic arithmetic with numbers (integers and decimals) * Arithmetic with numbers and Time Intervals * Operations between Time Intervals (addition, subtraction, and division) * Operations between Time Intervals and Time Points (addition and subtraction) * Operations between Time Points (calculating the difference) * Conversion between units of time * Conversion to and from POSIX Time * Conversion between time zones Date.Time Calculator is especially useful for questions such as: * What date is 100 days from today? * What date and time was it 32,768 seconds ago? * If one lap takes 1 minute 32.6 seconds, how long will 62 laps take? * What time will it be after those 62 laps? * How many days have passed since January 23 of this year? * How many days are 100,000 seconds? * What date and time does POSIX Time 1234567890 represent? * What is the current time in POSIX Time? And with a little creativity, Date.Time Calculator can be useful in many other situations as well.

Stadiametric Rangefinder is a range to the target estimation utility. It's designed to find distance to the target with a MIL, MOA, MRAD scale reticle fast and easy. The intuitive graphical interface was designed to replicate what you would actually see through your riflescope. Real-time calculations provide instant range measurements in yards or meters. You can also select any point in the world on map and location of the target on map and see how your target will look through eyepiece of your scope. Features: • Fast target distance estimation in both yards or meters • More than 3000 reticles. Including reticles from Carl Zeiss, Nightforce Optics, Kahles, Vixen Sport Optics, Premier Reticles, Primary Arms, Schmidt and Bender, SWFA, U.S. Optics, and Vortex Optics, US Army, USMC mil-dot ( see list of reticles supported here http://jet-lab.org/chairgun-reticles ) • More than 80 targets (IPSC, NATO, EIC targets). Also you can add targets for shooting created by you • Target size presets • Adjust for magnification setting (second focal plane) • Calculator for MOA at distance • Click value validator • Ballistic coefficient from 2 speed calculator • Angle units converter • Speed units converter • Weight units converter • Pressure units converter • Length units converter • Torque units converter • Air laboratory (Air Density, Density Altitude, Relative Air Density (RAD), Dew Point, Station Pressure, Saturation Vapor Pressure, Virtual Temperature, Actual Vapor Pressure, Cumulus Cloud Base Height, Dry Air, Dry Air Pressure, Volumetric Content of Oxygen, Oxygen Pressure) • Light/dark/gray color themes
