How to Calculate Stardates

Step-by-Step Guide

1. 1

   Step 1: Understand how long a year is.

   There are 1000 stardate units in one Earth year.
2. 2

   Step 2: Look at how long your year is.

   365 days normally, 366 for a leap year.
   
   This number is called n. , The base date will determine all of your other calculations.
   
   There are two base dates that you can use: 2005 =
   58000.00 and 2323 =
   00000.00 The standard year (2005 or 2323) is now called b and the stardate year (58000.00 or
   00000.00) is called c. , This number shall be called m.
   
   Here's a list:
   January = 0; February =
   31.
   
   For all other months, add one if it is a leap year.
   
   March = 59; April = 90; May = 120; June = 151; July = 181; August = 212; September = 243; October = 273; November = 304; December =
   334. , The day in the month is called d, and the year is called y.
   
   So, using 2005 as the base date, 23 May 2008 has these values: n = 366; b = 2005; c =
   58000.00; m = 121 (120, +1 for leap year); d = 23; y =
   2008. , The stardate formula is this: c + (1000*(y-b)) + ((1000/n)*(m + d
   -1)) = Stardate.
   
   Using the above values, the stardate works out to be
   61390.71.
   
   Stardates are usually quoted to two decimal places.

   Step 3: Choose a base date.

   Step 4: Calculate the "month number".

5. 5

   Step 5: Find the day and year.

6. 6

   Step 6: Put these values into the formula.
