Calculate your troll age from a human age or birth date in troll years or Alternian sweeps, plus your troll life stage and next wriggling day date.

A date of birth also unlocks your next wriggling day date.

Human Age to Troll Age Formula

The following formula is used to calculate the troll age for a given human age, and vice versa.

T = (H - 1) * 3 + 20

Variables:

  • T is the troll age
  • H is the human age

To calculate the troll age, subtract 1 from the human age, multiply the result by 3, and then add 20. Conversely, if you have the troll age, subtract 20, divide the result by 3, and then add 1 to calculate the human age. This formula offers a fun way to compare aging between humans and trolls.

Formula: Troll age T = (H − 1) × 3 + 20 = 3H + 17. Inverse: Human age H = (T − 20) / 3 + 1 = (T − 17) / 3.

What is a Troll Age?

Troll age is a concept used in fantasy literature and games to describe the effective age of trolls compared to humans. Trolls are often depicted as rugged, enigmatic beings with a unique aging process that differs from that of humans. The troll age calculator provides a playful tool to convert a human’s age into the equivalent troll age and vice versa.

How to Calculate Troll Age?

The following steps outline how to calculate the Troll Age.

  1. First, determine the human age (H).
  2. Next, use the formula T = (H – 1) * 3 + 20 to calculate the troll age.
  3. Alternatively, if you have the troll age (T), use the formula H = (T – 20) / 3 + 1 to calculate the human age.
  4. Finally, verify your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Human Age (H) = 25

Using the formula T = (H – 1) * 3 + 20, the troll age (T) would be:

T = (25 – 1) * 3 + 20 = 92
