Tecchilaw Calculator

How It Works:

Input: The user enters a value for a specific time unit (e.g., seconds, minutes, hours, days, weeks, months, or years).
Conversion: The script converts the entered value into seconds (the base unit for time) and then converts it into the target unit.
Output: The converted value is displayed in the selected target unit.

Supported Time Units:

Seconds (s)
Minutes (min)
Hours (h)
Days (d)
Weeks (wk)
Months (mo) (approximated as 30 days)
Years (yr) (approximated as 365 days)

Conversion Logic:

The value entered in the input field is converted to seconds first, using the corresponding conversion factor for the selected "from unit."
Then, the script converts the value in seconds to the target unit using the conversion factor for the selected "to unit."

Example Conversion:

If the user enters 1 year in the "from unit" and selects "days" as the "to unit":

1 year = 365 days (approximately).
The script converts 1 year to 365 days.

How It Works:

Input: The user enters a value for a specific astronomical time unit (e.g., Julian Day, Sidereal Day, Solar Day, or Light Year).
Conversion: The script converts the entered value into seconds (the base unit), and then converts it into the target unit.
Output: The converted value is displayed in the selected target unit.

Supported Astronomical Time Units:

Julian Day (jd): A continuous count of days since the start of the Julian Period on January 1, 4713 BCE. It is used by astronomers to calculate time.
Sidereal Day (sd): The time taken for the Earth to complete one rotation relative to the stars, approximately 86164.1 seconds (23 hours, 56 minutes).
Solar Day (sd_earth): The time it takes for the Earth to complete one rotation relative to the Sun, exactly 86400 seconds (24 hours).
Light Year (ly): While usually a distance unit, light year can be used for the time light takes to travel in one year (about 365.25 days or 31,557,600 seconds).

Conversion Logic:

The script first converts the entered value to seconds using predefined constants for each time unit.
Then, it converts the time value from seconds to the selected target unit using the conversion factor for the chosen "to unit."

Example Conversion:

If the user enters 1 Julian Day and selects Sidereal Day as the target unit, the script converts the Julian Day into seconds and then to Sidereal Days.

How It Works:

Input: The user enters a value for a specific specialized time unit (e.g., Fortnight, Epoch Time, Planck Time, Millisecond, Microsecond, Nanosecond, or Picosecond).
Conversion: The script converts the entered value into seconds (base unit), and then converts it into the target specialized time unit.
Output: The converted value is displayed in the selected target specialized time unit.

Supported Specialized Time Units:

Fortnight (fortnight): A unit of time equal to 14 days (or 1209600 seconds).
Epoch Time (epoch): The number of seconds since January 1, 1970 (Unix time). It's a standard time representation in computing.
Planck Time (planck): A very small unit of time (approximately 5.391247 × 10⁻⁴⁴ seconds) based on Planck's constant.
Millisecond (ms): One thousandth of a second (0.001 seconds).
Microsecond (µs): One millionth of a second (1e-6 seconds).
Nanosecond (ns): One billionth of a second (1e-9 seconds).
Picosecond (ps): One trillionth of a second (1e-12 seconds).

Conversion Logic:

The script first converts the entered value to seconds using predefined constants for each time unit.
Then, it converts the time value from seconds to the selected target unit.

Example Conversion:

If the user enters 1 fortnight (14 days), and selects seconds as the target unit, the script will convert it to 1209600 seconds

How It Works:

Input: The user enters a value for a specific computational time unit (e.g., Clock Cycle, CPU Time, Tick, Quantum Time, or Instruction Cycle).
Conversion: The script converts the entered value into seconds (the base unit), and then converts it into the target computational time unit.
Output: The converted value is displayed in the selected target unit.

Supported Computational Time Units:

Clock Cycle (cycle): The time for one CPU cycle, typically around 1 nanosecond.
CPU Time (cpu): The time taken by the CPU to process an instruction, often close to a clock cycle.
Tick (tick): A unit of time used in system timers, usually 1 microsecond.
Quantum Time (quantum): The time slice allocated for a process in a CPU, often 1 millisecond.
Instruction Cycle (ic): The cycle time of a single CPU instruction, typically around 1 nanosecond.

Conversion Logic:

The script first converts the entered value into seconds using predefined constants for each time unit.
Then, it converts the value from seconds into the selected target computational time unit.

Example Conversion:

If the user enters 1 Clock Cycle (1 nanosecond) and selects Tick (1 microsecond) as the target unit, the script converts the clock cycle into seconds and then into ticks (1 microsecond).

Units and Approximation:

Clock Cycle and Instruction Cycle are typically very fast, on the order of nanoseconds.
CPU Time may be similar to a clock cycle but could differ based on CPU speed.
Tick is usually a larger unit, often around 1 microsecond.
Quantum Time is usually a time slice used in multitasking systems, often 1 millisecond.

How It Works:

Input: The user enters a time value for a specific geophysical time unit (e.g., Julian Year, Sidereal Year, Tropical Year, Eon, Era, Epoch).

Eon (eon): A long period of time, typically 1 billion years.
Era (era): A geologic time unit, typically around 10 million years.
Epoch (epoch): A unit of time typically representing 1000 years.

Conversion Logic:

The script first converts the entered value into seconds using predefined constants for each geophysical time unit.
Then, it converts the value from seconds into the selected target unit.

Example Conversion:

If the user enters 1 Julian Year and selects Tropical Year as the target unit, the script converts the Julian Year into seconds and then into Tropical Years.

Units and Approximation:

Julian Year approximates Earth's orbit as 365.25 days.
Sidereal Year is slightly longer than the Julian Year by a few hours (365.25636 days).
Tropical Year is slightly shorter than the Julian Year, accounting for precession (365.242190 days).

Epoch is used in historical and astronomical contexts, representing shorter periods, typically around 1000 years.

How It Works:

Input: The user enters a time value for a specific calendar or international time unit (e.g., Gregorian Year, Julian Day, Week, Month, Day, Hour, Minute, or Second).

Then, it converts the time value from seconds to the selected target unit.

Example Conversion:

If the user enters 1 Gregorian Year and selects Month as the target unit, the script converts the Gregorian year into seconds and then into months (approximately 12 months).

Units and Approximation:

Gregorian Year accounts for leap years, making it slightly longer than a standard year (365 days).

Week and Month can vary in length, but this calculator uses average values for simplicity (e.g., a month is considered to be 30.436875 days).
Day, Hour, Minute, and Second are based on standard time divisions.

How It Works:

Input: The user enters a time value (in a chosen financial/business time unit).

Example Conversion:

If the user enters 1 Business Day and selects Week as the target unit, the script converts the Business Day into seconds and then into weeks (approximately 0.2 weeks).

Units and Approximation:

Business Day: Assumes a standard 8-hour workday, but this can vary depending on the country or industry.
Week, Month, Quarter, and Year: These units are approximated based on averages, as actual lengths may vary slightly (e.g., a month may range from 28 to 31 days).
