It is an entertainment score, not a judgment about this friendship.<\/p>\n<p>\n\r\n<\/section>\n<h2>How to use the calculator<\/h2>\n<ol>\n<li>Enter your name in <strong>Your Name<\/strong> and the other person\u2019s name in <strong>Friend's Name<\/strong>. Neither field can be empty.<\/li>\n<li>Check <strong>Your Date of Birth<\/strong> and <strong>Friend's Date of Birth<\/strong>. Both date fields initially show a date 20 years before your visit, so replace them with the intended birthdays.<\/li>\n<li>Choose an option in <strong>Your Gender<\/strong> and <strong>Friend's Gender<\/strong>. These selections contribute a small fixed amount to the calculation.<\/li>\n<li>Calculate and read <strong>Your Friendship Strength<\/strong> as a percentage. You can change an entry and calculate again to see how the score changes.<\/li>\n<\/ol>\n<h2>What the friendship compatibility score means<\/h2>\n<p>The result is a number generated from the entries, not a test of how well two people get along. The same inputs normally produce the same result, so the score is not random. It does not consider shared experiences, trust, communication, or whether either person enjoys spending time together.<\/p>\n<p>A higher percentage means only that the inputs produced a higher total under this particular rule. A 75% result does not mean a friendship has a 75% chance of succeeding, and a 34% result does not suggest a problem. Use the number as a conversation starter rather than a rating of either person.<\/p>\n<p>The name calculation is especially important to interpretation: it recognizes the Cyrillic letters listed below, but not Latin letters. If you enter names using the English alphabet, their letters add nothing to the name value. The dates and gender selections can still produce a result, so the displayed percentage may look meaningful even though the names did not affect it.<\/p>\n<h2>How names and dates affect the result<\/h2>\n<p>The calculator converts names to lowercase and removes spaces before adding letter values. Each occurrence counts: a repeated letter contributes its value again. It combines both names before dividing the letter total by two; it does not calculate a separate score for each person. The recognized letters have these values:<\/p>\n<table>\n<thead>\n<tr>\n<th>Value<\/th>\n<th>Cyrillic letters<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>1<\/td>\n<td>\u0430, \u0438, \u0441, \u044a<\/td>\n<\/tr>\n<tr>\n<td>2<\/td>\n<td>\u0431, \u0439, \u0442, \u044b<\/td>\n<\/tr>\n<tr>\n<td>3<\/td>\n<td>\u0432, \u043a, \u0443, \u044c<\/td>\n<\/tr>\n<tr>\n<td>4<\/td>\n<td>\u0433, \u043b, \u0444, \u044d<\/td>\n<\/tr>\n<tr>\n<td>5<\/td>\n<td>\u0434, \u043c, \u0445, \u044e<\/td>\n<\/tr>\n<tr>\n<td>6<\/td>\n<td>\u0435, \u043d, \u0446, \u044f<\/td>\n<\/tr>\n<tr>\n<td>7<\/td>\n<td>\u0451, \u043e, \u0447<\/td>\n<\/tr>\n<tr>\n<td>8<\/td>\n<td>\u0436, \u043f, \u0448<\/td>\n<\/tr>\n<tr>\n<td>9<\/td>\n<td>\u0437, \u0440, \u0449<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>For birthdays, the calculator adds the two days and reduces that sum to one digit. It does the same with the two months and the two full years. This differs from reducing each person\u2019s birthday separately.

A result at either boundary may represent a calculated total outside that range; it is not an exact measurement rounded to the nearest percent. Matching gender selections add 2 instead of 1, but that rule is arbitrary and says nothing about whether people of any genders can be good friends.<\/p>\n<p>The calculator reads dates through your browser. In some time zones, its date handling may interpret a selected date as the previous calendar day, which can change the score. If a worked calculation does not match the displayed result, this is one possible reason.<\/p>\n<p>For another playful comparison, see the <a href=\"https:\/\/wpcalc.com\/en\/life\/love-strength-calculator\/\">Love Strength Calculator<\/a>.
