RE: Top three calculators ?
The three that I go to most often.
1. m48+ on iPad 2. DM42 3. HP41cx Alternatives that I really enjoy: HP15C WP 34S i41CX+ on iPad I am also waiting for the next group of 41CL boards. In my case it is  So many calculators and so little time John

BASIC: This formula is from Zeller's congruence: \(h=\left(q+\left\lfloor {\frac {13(m+1)}{5}}\right\rfloor +K+\left\lfloor {\frac {K}{4}}\right\rfloor +\left\lfloor {\frac {J}{4}}\right\rfloor 2J\right){\bmod {7}}\) where
NOTE: In this algorithm January and February are counted as months 13 and 14 of the previous year. Here's a possible implementation for the HP48G: ( mm dd yyyy  dow ) Code: « ROT Using local variables helps to avoid stack acrobatics. It makes code maintainable without the need of pseudocode in comments. My rule of thumb is not juggling with more than three objects on the stack. Valentin is able to write BASICcode for the HP71B that I often don't understand at a first glimpse. But that's okay when he's playing code golf. Thus it's not so much about the language but about your attitude when writing code. I agree with you though in terms of RPN due to its lack of local variables and means to structure code and data. There it helps to have a mapping of variable names to registers, stackdiagrams or the implementation of the algorithm in a language like Python. Kind regards Thomas I had a hard time understanding your code but that was more related to the question of why you used a different formula for handling m? Just so you can start the list of weekdays with "Sunday" instead of "Saturday"? Or is it based on a different source for the algorithm? Or then why don't you reuse c in the calculation of d? Code: c = int(yr/100) BTW: There's a typo in your RPL code: "Thrusday" → "Thursday"

I'd probably have the Prime Pro for Android except having paid for the hardware I'm not paying again for the app. Geoff

RE: Top three calculators ?
I do computations in R and Python for a living, so most of the time my calculation/computational tools are workstation to clustersized, but for those times when calculators are preferred or more convenient:
1. HP 15c (both original, one of which I purchased new in 1988). I keep one at home and another at work, and they both get regular use. 2. HP 16c. I noodle around with 8bit assembly programming (8085, 6502, and starting to play with the Z80), and the 16c is a great companion for this. 3. HP 48sx. I play around with this just for fun. Something new might make the list, however, as I will soon be receiving an HP 71b.

RE: Top three calculators ?
For me:
Honourable mentions to the HP 42S / DM 42S and HP 32sii which I also use regularly. I'd also love to have an HP 97 on my desk at work.... Or teenix's new desktop device when it comes out Pauli

RE: Top three calculators ?
1. HP67 (once its card reader is repaired, what a jewel!)
2. HP41CX (attempting to code a fuel/alcohol car combustion program) 3. HP25C (to repair or Panamatik's candidate). Well... I voted twice, nevertheless "based on a daily usage", it remains true.

RE: Top three calculators ?
Based on daily usage and sitting on my desk:
1. HP48G  it just feels right, like a perfectly fitting glove 2. HP12C  quick calculations, and I use it's financial capabilities quite often 3. TI89 Platinum  playing with CAS, experimenting with mathematics Patrick

RE: Top three calculators ?
1) WP34S app  most frequently used for quick calculations by far, but hardly ever anything fancy that could not be done on a HP35.
2) HP15C/32S whichever is nearer 3) HP50G although I am miles away from even grasping what it can do. I just seem to have more calcs than calculations.....

RE: Top three calculators ?
1) HP67. It's on my desk at home and unless there is a reason not to, I will always gravitate towards it. Love the red LEDs especially because the lighting in my home office is usually dim. There is a definite pleasure in using it  much like using my old Leica cameras or a fine fountain pen  neither too practical, but an irrational joy to use.
2) HP15c. From a feature and layout standpoint, this is probably the ideal calculator for me. For more complex tasks it is invariably what I reach for. Just the right balance of depth and ease of use. I use the LE but I don't think that's really relevant. If I could get a 15c with a red LED display (or better yet Nixies!) would never look at any other calculator again. 3) Tough to pick one to finish off this list. At this point I have probably spent more time with the WP34s than any other calculator and I like it conceptually, but the buttons of the base calculator are lousy and I get frustrated with always having to reach for the reference manual. I might have to choose the 35s  the ergonomics are good, the build is decent, I like the feature set, and unlike all my copies of the 32sii, it just works.

RE: Top three calculators ?
1. Naive Design ND1 for iOS (very good program, though the support forum is down again).
2. WP34S for iOS. 3. HP Prime  physical and iOS versions. DGM

RE: Top three calculators ?
1. HP16C (and any Voyager)
2. HP48GX (esp. the ones with the Black LCD screen) 3. HP28S Voyagers are legendary. HP28S is beautiful. Had to return one recently as it had the battery door issue. But the keypad was sublime.. I don't think I have ever used better. LCD was super sharp as well... and it was fast! Also HP71B is great. Worst. 1. HP48S/SX's... the LCD's were terrible, they were so hard to see, and almost impossible in poor light 2. HP49's.... hated by every HP48 owner! 3. Anything newer than 2000 ))))) HP28S (1988 US model), DM41X (2020)

RE: Top three calculators ?
Hardware:
1. HP32E (my favourite Spice) 2. HP12c (I collect Voyagers & am in search of the 5 Brazilian HP12c Prestige) 3. HP41C, HP15c Software: 1. HP15c simulator of Torsten Manz 2. WP34s 3. HP32E emulator of Panamatik (HP01 and other Woodstock/Classic emulators of his are nifty as well) 4. New kid on the block since Allschwil'18: Virtual HP41 Release 9 (HPIL builtin!) BTW: All of these calculators in software work excellently "out of the box" under Wine (Linux or Intel MacOS). When it comes to important figures, I trust the calculators more than a spreadsheet ... As a rule of thumb: every calculator comes in three: 1x work, 1x home & 1x as reserve (“...still echoing in his brain: The Ramans do everything in threes.”)

Quote:(“...still echoing in his brain: The Ramans do everything in threes.”) Most unfortunately because, while "Rendezvous with Rama" is truly excellent, the two subsequent sequels are just textbook examples of blatant money milking.
