Hjalmar is a first name for boys.
Recently, the name Hjalmar has been given only a handful of times a year and is therefore particularly rare, at least in the US. In recent years, not even one boy in 100,000 has been named Hjalmar. That means that a boy named Hjalmar is exceptional and may not meet another person with the same name his whole life.
Well, you might say, you probably figured that out yourself! But what you might not know is: The letter H is not particularly common as a first letter for boys' names: only 2.9% of all common boys' names in the US begin with an H. The most common first letters for boys' names are J and A, while X and U are the least common first letters of boys' names.
With seven letters, the name Hjalmar has a typical length for first names in the US. In fact, 26% of all common first names consist of exactly seven letters. 52% of all first names are shorter, while 22% have eight letters or more. On average, first names in the US (not counting hyphenated names) are 6.5 letters long. There are no significant differences between boys' and girls' names.
This means that if 2.9% of all boys' names begin with an H, this initial letter is less common than the other letters on average. Nevertheless, there are of course some names that begin with H and are extremely popular, for example Henry, currently the most common boys’ name with H.
If your name is Hjalmar and someone asks after your name, you can of course just tell them what it is. But sometimes that isn't so easy - what if it's too loud, and you don't understand them well? Or what if the other person is so far away that you can see them but not hear them? In these situations, you can communicate your name in so many other ways: you call spell it, sign it, or even use a flag to wave it...
So that everyone really understands you when you have to spell the name Hjalmar, you can simply say:
Braille is made up of dots, which the blind and visually impaired can feel to read words.

These flags are used for maritime communication - each flag represents a letter.
In the navy, sailors of two ships might wave flags to each other to send messages. A sailor holds two flags in specific positions to represent different letters.
In Morse code, letters and other characters are represented only by a series of short and long tones. For example, a short tone followed by a long tone stands for the letter A. Hjalmar sounds like this:
