In the Star Trek universe we do see recognition of  - Federation Day, First Contact Day, and, of course, birthdays. When are they celebrated? Every planet has a different year, so do they go by the earth year? Year of the planet they're closest to? Does Kira celebrate a birthday every Bajoran year and O'Brien celebrate his birthday every Terran year? (Which could lead to them having coinciding birthdays some years and not others.) When people's ages are reported on personnel or medical forms, do they use a single standard or a relative one? (I'm 24 in earth years, but 15 on my home planet.) How about major events like holidays? How do they know when to celebrate Federation Day or the Bajoran Gratitude Festival?

I've noticed that there seems to be a noticeable absence of 'public holidays' in the Star Trek universe.  I imagine that the fact that we're normally with Starfleet personnel would impact this, but do we have any evidence to support that public holidays (on Earth specifically) still exist in the 24th century?

I have found references to birthdays and "deathdays," many words that reference either death or birth (natalis, obitus, quietus) but not both sharing the same day and month (even sharing the same year in the case of some children).

In the Star Trek TNG episode , the away team find the remains of an astronaut, his uniform had an American flag with 52 stars     On the sleeve is a version of the United States flag with 52 stars    Digging a bit further, the Memory Alpha page about the , states that in the year 2033, in regards to this:     The US added a 52nd star to its flag, indicating the inclusion of a 52nd state to the union. The flag had 52 stars until 2079   What states do the extra 2 stars represent?  Also, why did this number change in 2079?

Is there a commercial service offered to general public that allows you to celebrate the new year several times?  The idea is that you would celebrate it in a time-zone and than move to the next one arriving there before new year. Of course this is relatively easy to accomplish by yourself if you're near the border of a country and you just move to the next one in a different time zone. Things probably get a bit more complex to do it 3 or more times.

Recently, I've decided to make it a personal task to watch through ALL of Star Trek.  I grew up on TNG and watched it whenever I could.  I mention this because I have a distant recollection of many of the stories I loved from TNG, but now that I'm more thoroughly watching through the original series, I'm starting to have personally "haunting" questions that make me curious about the Star Trek universe and why certain events played out the way that they did.  I've noticed that in TOS throughout at least the first season alien races tend to fall into two classifications-- humanoid races that, in regards to intelligence and strength, are much on-par with humans.  This includes Vulcans, Romulans &amp; Klingons and a few other incidental races that come and go as needed for a particular story.    There is also a second set of alien races that are not slightly but are rather significantly evolved beyond humans.  These races tend to appear in one episode, do their "unbelievable" acts and conclude the episode assuming we never hear from them again, often for the sake and safety of humanity.  These races include the people of Talos IV that could manipulate the perceptions of minds, the beings from "The Squire of Gothos" that could control entire planets and the Organians which were excessively peaceable people that were capable of seizing up all weaponry aboard all Klingon and starfleet vessels in the vicinity of their system.  QUESTION  Much of my knowledge of the Star Trek universe comes from my childhood watching of TNG.  In TNG we saw multiple interactions of the Enterprise crew with Q and his race.  The Q was, to my knowledge, the only major race encountered that was significantly more advanced that humans.  This is quite a juxtaposition to season #1 of TOS, where in every few episodes we see a new race that has unbelievable powers capable of doing nearly anything imaginable.    It is my understanding that the Q stayed out of the galactic war with the Borg because they believed in letting the rest of the universe play out at its own pace, in its own way.  This is why they never wiped out the Borg or provided limited protection for the United Federation of Planets.  However, as outlined above, in TOS many exceptionally intelligent and capable races existed that could take control of people, manipulate space/time or simply do whatever they wanted to do.  Where were these races in the war against the Borg?  Were any of them ever contacted by starfleet and asked for assistance?  Were any of them assimilated?  Were they just out of site and out of mind as if they weren't part of the galaxy?  In my opinion, from the perspective of TOS there were NUMEROUS races that seemed capable of stopping or potentially destroying the Borg.  Where were they during the time of The Next Generation and its subsequent movies?  I'm not really asking for a speculative answer, however, I am curious if this was ever addressed in any post-TOS material whether on the television show, in comic books or novels.

In  the main character (he is a mathematician) calculates the day of the week of someone's birthday (19/07/1992 is Sunday). I know (very) basic modular arithmetic but I can't figure out how to do it. Can someone point me to the right direction? It seems fun to do.

Does any species, in any age, in any of the works by Tolkien have designated days of celebration, except birthdays, besides the holidays mentioned in the  on Wikipedia?

Many times I have read statements like, "the age of the universe is 14 billion years" . For example this wikipedia page .   Now, my question is, which observers' are these time intervals? According to whom 14 billion years?

We see that in DS9 the Bajoran religion is alive and kicking, but I've never seen any mention of a religion that came from Earth, or one practiced by humans.  Are any of Earth's religions still practiced in the current setting for Star Trek in the 23rd 24th century, or have they all died out? If they have 'died out', is this ever mentioned?

Watching Star Trek made me think of a few "deeper" questions about Starfleet, which are all related to the Star Trek TV series.  So, let's take for example the Dominion War: people are dying every second, ships get destroyed and cadets are still joining although they know they are probably going to die unless they are with Picard or Sisko.  As I read and got to understand, money has no value anymore, latinum is the general trading currency in the universe. But people on Earth don't trade and don't earn their paychecks. Earth is a much better place than today and yet young boys and girls from every culture/civilization are joining Starfleet as they are willingly signing their death note.  Why are they joining, what motivates them? They might know that they're probably going to die.  They don’t earn paychecks. They could be doing any other job, yet they choose this. And what's more interesting how many died on battlefields must be lined up in front of StarFleet every day?  What do they receive after service? Why are they doing it other than preserving their homes?

In the TNG episode "", we are treated to the following line of dialogue...three times.       "Captain's Log, Stardate 45652.1. The Enterprise has entered an area of space known as the Typhon Expanse. We are the first Starfleet vessel to chart this unexplored region."    This strongly suggests that no Starfleet ship has ever actually been into this part of space.    Yet the very end of the episode shows that a Starfleet ship WAS in this section of space, Specifically the USS Bozeman, years ago. Proven when it emerged from a temporal loop just in front of the Enterprise.    How do we account for this inconsistency - saying that the Typhon Expanse has never been charted, and yet there clearly being a federation ship already in the Typhon Expanse?

Some things are best read/viewed in the order of release, regardless of chronology.  Some works are better taken in a sequence that reflects the order of the events represented.  And for some others, it's a blend of the two.  I'd like to introduce my 8-year old daughter to the Star Trek franchise, and hope to eventually cover it completely.  That is, to fully include:   TV series   The Original Series The Next Generation Deep Space Nine Voyager Enterprise  Movies   The Motion Picture Star Trek: II - VI Generations First Contact Insurrection Nemesis Star Trek (2009) Star Trek Into Darkness (2013)    I've found a * that seems to thoroughly cover the chronological order down to individual episodes.  Should I use this, or should I go in order of release?  Or, is there another recommended alternative order?  I am not interested in any answers that recommend exclusion of any series, episode, or movie from those listed above.  However, lists that add more content are certainly welcome.  Also, unless someone offers a compelling reason to do otherwise, I'm planning on leaving the 2009 movie for last since it represents the beginning of a completely new canon.  *On a slightly related note, it would be really nice if somebody with sufficient time and resources could add episode numbers to that list.

It seems there may be a bit of a retro-continuity error in one of my personal favorite Star Trek scenes, which I noticed just today.    Click the picture above for a YouTube video.  A transcript of the pertinent bits is below, emphasis added.     SCOTTY: The Enterprise!  Show me the bridge of the Enterprise, you chattering piece of...        COMPUTER: There have been five Federation ships with that name.  Please specify by registry number.        SCOTTY: N, C, C, one, seven, oh, one.  No bloody A, B, C, or D.   The computer is specifically stating that there have been (only) five Federation ships named Enterprise.  Scotty effectively names all of the ones we'd been introduced to by the time of that episode:  NCC-1701, NCC-1701-A, NCC-1701-B, NCC-1701-C, and NCC-1701-D.  However, this of course omits the NX-01.  Out-of-universe, this can easily be attributed to the history of the television series.  However, I'm wondering if there might also be a (possibly un-intended) in-universe explanation that allows the computer's statement to still be accurate?  For example, (and I only ask because I'm not too familiar with the Enterprise series just yet) does the NX-01 Enterprise actually pre-date the existence of the United Federation of Planets?

The series Star Trek: Discovery, due to be released in early 2017, will be the first new Star Trek series since Enterprise. According to :      Set to premiere on CBS in January 2017 before moving to All Access,   the series will introduce new characters to the Star Trek franchise,   and will not be related to the 2016 film Star Trek Beyond.   The same article mentions that it will take place in the original timeline.   Has there been any confirmation of what year the series is set in? Is it before or after Star Trek: Beyond?

There is a small difference between intro texts in TOS:     Space: the final frontier. These are the voyages of the starship Enterprise. Its five-year mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before.   and in TNG:     Space: the final frontier. These are the voyages of the starship Enterprise. Its continuing mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no one has gone before.   (emphasis mine)  It's pretty obvious that no man was changed to no one to include women. But, is there any explanation why was five-year changed to continuing? Also, why was it a five-year mission at all?  My only assumptions are:   Gene Roddenberry hoped to get funding to run the show for 5 seasons. Gene Roddenberry just made up a number without any special meaning. Gene Roddenberry was a .   Is there any official explanation, in universe or not?

In my daughter's class of $23$, three students and the teacher all share the same birthday. Of course, there are $365$ days in the year, and the first case of the shared birthday is not counted in the probability. But is the likelihood of this just $$\frac{1}{365}\times 3 = 0.0082?$$ For my curiosity, leap years can be omitted.

Much like we use B.C.E and A.D, in the Star Wars universe they use B.B.Y and A.B.Y, standing for Before Battle of Yavin and After Battle of Yavin respectively.  But what date system had the galaxy used before the events of Episode 4?
