| A collection of editable functions for the HP 50g including Julian, Gregorian and my own DTime time calculations and conversions and time prettyprinting, MegaPixels, scaling, number of digits in an integer for a given base, conversion of real to integer by lopping off anything after decimal point (not like ceil and floor), zeropad for number string output, a BMI calculator for adults, and a function for converting numbers to fixed point SI units or IEC units, a download time estimator, an inform function for calculating time left given 2 DTime timestamps and a percent, all as editable individual program files. The time library allows you to multiply, divide, add, subtract time using DTime as the base time format. The time calculator can be used for long download time calculations for a given bandwidth. Lots of daily-useful functions oriented mainly towards computer science and computer usage. |
Analog clock and paging calendar. Clock runs with high precision also while paging through the month. Autostart-functionality with "blind" turn-off. ACC is very small because it's a self-extracting code, applied here for the first time).
ACC (Analog Clock with paging Calendar) in various languages. Clock keeps running with high precision also while paging the calendar. Autostart after a "blind" turn-off. ACC is a small self-extracting code applied here for the first time. Languages: Besides in the 6 indicated languages also in Dutch, Esperanto, Finnish, Polish. American English version is a separate package named ACC.
Small and fast tool for adjusting time in seconds, minutes or hours, also for fast switching between summer and winter time. Can easily be integrated in the builtin TIME choose box.
A small but comfortable and easy to use clock adjustment and calibration tool for the HP 49 clock. All manipulation is made in a graphic environment on a running analog clock. Includes independent DST and Time zone switching.
A fast and comfortable alarm maker, with repeat intervals of precisely one or several years, same day and time. Contains also a Cuckoo alarm making a clock from your HP 49 but the Cuckoo calls at desired hours only. Alarms run with dark display to make the sound nicer and to save the batteries.
Analog clock for the 49G and 49g+.
Huge digital clock written in System RPL that uses the Disney Print font.
This is a handy dandy bus schedule program with a fancy analog clock.
Displays an analog clock and a calendar. Written in System RPL.
CalConvert converts Gregorian dates to Jewish dates and vice versa.
Shows the calendar of the current month which is paging through the months. Written in ASM, so it's VERY fast.
Calendar for every year, with all the holidays including Carnaval and Easter. Only works with dd.mmyyyy date format.
This program, written in assembly language, shows a calendar with a grayscale background. For the HP 49G with ROM 1.19-6.
Chess clock written in System RPL.
Chronometer is a chronometer-style set of commands written in very fast internal, comprising of the most necessary routines for keeping track of time.
Most HP 49G clocks are not very accurate. One second a day may not seem to be much, but will sum up to a minute in two months. Additionally, the temperature of the HP 49G, and therefore the usage of the calculator, influences the clock speed. ClckAdjst is a library, which provides tools for "automatic" clock adjustments and much more. ClckAdjst provides fast and easy setting and adjustment of the system clock. It handles changes of the time zone and automatic daylight saving time changes for USA and Europe. It provides an accurate "automatic" clock adjustment and shows the daily deviation of your HP 49G/g+ clock.
Chronometer/stopwatch written in System RPL.
The program creates a variable (best viewed using MKLBL program found on this fine web page) containing the JMFD's mnemonics string for the specific date, either using HP 49 command DATE or any other in the format.
Contains many date and time functions, including when Easter is, what the current GMT is, the Julian date, the week number, and more.
Enter a date and get the day of the week.
Puts a digital clock in the middle of the screen.
Returns the number of years, months and days between two dates. It takes 2 real arguments like the internal command DDAYS. The level 1 date must be chronologically later than the level 2 date. Includes source code. Provided in a library (DYMD.HP).
Fast and easy to use calendar program. Shows the current month or an arbitrary day. Commands to increase/decrease the month/year help for fast navigation.
Tells the time from around the world. Also displays the current "Internet time". Too bad it's buggy and bloated.
Shows the current time using the Swatch iTime standard.
Opens a message box with the current Julian Date in full format.
Provides a running display of the time in Julian format.
MultiStopwatch is a library for the HP 49g+/50g (only) that provides standard stopwatch functions, but with the following additional features: 3 independent timers per data file, with a real-time console application to show them, console app manipulates timers at native Saturn speed (not ARM, but as accurate as is feasible with the clock on these systems), data is maintained between sessions, so the timers continue to run while performing other operations on the calculator. Can be run from ports 0-2. Most stopwatch functions have corresponding User RPL commands available. Supports printing to the HP 82240B (or compatible) printer.
Shows the world map, local date and time, and the noon meridian during day time in Asia, Europe and America with high precision. DST switching added. Useful also as autostart informator in Date&Time, including local time on nearly the whole world. The package also contains a tiny but powerful animator named ANI (with speed and direction switch, standby etc) and a sample of examples to explain the use of ANI in self-made animations.
The program creates a list containing the JMFD's preferred string for the actual date, storing it in the variable AHORA49 in the format: { { "Tuesday, January 15, 2002" } {19.4104 } }
Stopwatch library which allows other calculations or programs to be run while timing.
Use your calculator as a stopwatch to record lap times. If you don't restart it or quit the program it will record laps even after turning off the calculator.
Assembly language stopwatch/chronograph, ported from the 48.

Allows setting setting date and time in a nice graphic environement with a running analog clock and a (month) calendar. The clock hands are moved with some keys as if you would move them on a real clock with your finger tips. Powerful calibration tools for the HP 49 clock are included as well. One can virtually browse through the calendar, in steps of a day, a week, a month or a year, even through the centuries. Thus, you see how the month calendar looks ten years from now, say, and make your plans. You can also easily set date and time after a battery collaps etc. There is also a world map with a moving noon meridian. Hence, so you'll know where it is noon at present. You can also set the 24 time-zone and in this way readily determine the local time of big towns in the whole world. Included are also fast alarm tools which allow setting repeat alarms of precisely one or several years, impossible with builtin tools. And you may play your own wake-up melody. Documentation in HTML.
WDAY is a universal calendar program written in User RPL. It provides a number of useful function I have not seen on other calendar/time programs, and has a fully commented source file. It can display the calendar of the month, day of week from date, number of days between two dates, Julian Day from date and date from Julian Day, differential date, and the Friday the 13th for any year.
Extended Time, Date, Calendar and Astronomical routines for the HP 48G(X) and 49G(+). Part of these routines are ported from the invaluable HP-41C CALENDARS Users' Library Solutions. The astronomical routines include calculation of times of sunrise, transit and sunset, moon phases, and seasons.
Calendar time and astronomical routines for the HP 49G(+). Part of these routines are ported from the invaluable HP-41C CALENDARS Users' Library Solutions. The astronomical routines include calculation of times of sunrise, transit and sunset, moon phases, and seasons. Version 2 is more user friendly than version 1.1 in that INFORM and INPUT forms and a CHOOSE box have been written for the most important conversions. In version 2.1 user input is further improved. The separate subroutines have been maintained for those who want to use them for their own calculations.
"Zoomed" clock, with a large time display and a smaller date display.
World time clock for the 49G/g+.
