The Holeman Simplified Calendar ( HSK)

General Introduction

The Holeman Simplified Calendar ( HSK) is a simple decimal based calendar system designed to replace the Gregorian calendar in wide use today. It is based on the fact that humanity will not be stuck on earth forever and having a consistent calendar ready to hand will be most beneficial. It has no leap units.

Instead of being stuck with base units of days and years, which are dependent upon which celestial body one happens to reside on at a given moment, HSK makes no assumptions of this nature. Note that is does not have any system in place to handle changes in gravity & speed which lead to time dilation, as when on a high-speed, sublight vessel; however, given its greatly simplified and consistent nature, the HSK lends itself to such far more readily than any current modern calendar system.

The Shift (symbol: shf ) is the base unit of time in HSK, which in turn is based on the second in the International System of Units (SI, 2.1.1.3) . One shift is defined as:

28,800 x the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom. (1 second)

In practical terms, this means that:

1 Shift = 8 Hours.

Year zero is based the epoch event of first time man sets foot on Mars. This will begin the year 1 PD. We are therefore living in a negative number PD, but have no way of knowing what year we are currently in. As of September 2014, estimates and guesswork put the current year at roughly -14 PD to -32 PD.

The abbreviation for the calendar is PD, and stands for Post Diaspora . It was inspired by David Weber's Honorverse series of books.

    Formatting

    Standard Format

    Y¦SSS:BBB.X

    Year *<pipe> 3 digit Shift <colon> 3 digit Beat <dot> Beat decimals **

    *Year is expressed with an as-many-as-need number of digits.

    **Beat decimals are optional, and are typically not used. Beat decimals are also expressed with an as-many-as-need number of digits.

    Alternate (Casual) Format

    Y¦HHSS:BBB.X

    Year *<pipe> Month Abbreviation , 2 digit Shift <colon> 3 digit Beat <dot> Beat decimals **

    *Year is expressed with an as-many-as-need number of digits.

    **Beat decimals are optional, and are typically not used. Beat decimals are also expressed with an as-many-as-need number of digits.

    Any unneeded portion can be left off when a level of clarity is obvious, as with any calendar system.

    Format Examples

    Starting at Years

    2186¦ (The start of the year 2186.)

    2186¦500 (Exactly halfway through the year 2186.)

    2186¦Des91 (Three earth "days" before the start of the year 2187.)

    2186¦250:320 (A typical date and time format, common usage for scheduling an appointment.)

    2186¦084:521.895198 (Near the end of the first month -Washah- in the middle of a shift. This has six digits, and is a very precise time. It would likely be used in a scientific report nictitating an extraordinarily precise time. )

    Starting at Months

    ¦500 (Halfway through the current year. Note the pipe to clarify this is a month, not the year 500.)

    ¦Hex (Halfway through the current year. Note the pipe to clarify this is a date, not a reference to the month in general. This is the same as the previous example.)

    333:600 (About 1/3rd of the way through the year. Note the lack of a pipe, which is not needed as there is a colon, indicating this is a date/time.)

    ¦Hex13:300 (The 13th shift of the sixth month -Hexios- about 1/3 of the way through the shift. Note the use of a pipe, which is redundant as the month name was used in abbreviated format.)

    ¦250:750 (A quarter of the way through the year, three-quarters of the way through the shift. Note the pipe making it abundantly clear that this is a date/time.)

    Nin:250 (The start of the ninth month, ¼ of the way through a shift. Note that as the abbreviation was used, the 2rd and 3th digits were dropped, indicating the 1st shift of the month.)

    ¦Bay18 (The 18th shift of the 8th month.)

    Chiy15 (The 15th shift of the 7th month.)

    Starting at Shifts

    :500 (Halfway through a shift. Perhaps lunchtime if it's a work shift.)

    :005 (Right near the beginning of a shift.)

    :001 (Exactly 28.8 "seconds" after the start of a shift.)

    :031.25 (Exactly 15 "minutes" after the start of a shift.)

    A Note on the Name of HSK.

    HSK is part of the Holeman Simplified Systems (HSS), which includes Holeman Simplified English (HSE). It therefore utilizes the HSE alphabet, which does not contain the letter "C." The letter "K" is used in all instances where a hard "C" would be found in standard English.

    You will also note that the month abbreviations are all two characters wide when expressed in HSE.
