When you are 20 years old you will celebrate your 250th month birthday. You'll be 41 when you turn 500 and when you're 62 you'll pass 750 months and when you're 83 you'll have your 1000 month birthday.
When you're 19 you'll pass 1000 weeks old, when you're 38 you'll pass 2000 week old, when you're 57 you'll pass 3000 weeks and 4000 weeks when you're 76, and 5000 weeks when you're 95 years old!
You turn 10,000 hours when you're 11 years old, you are 20,000 hours old when you hit 22, and 30,000 hours when you are 34, 40,000 hours when you're 45 years old and 50,000 hours when you're 57 years old.

I wish I could get birthday gifts on these mathematical birthdays.
Thank god I can celebrate my 20,000 hour birthday next year. I was worried I'd have to wait until I was 27 to celebrate a mathematical birthday
It's my 10,000th day birthday today! I already had it in my calendar luckily; wouldn't want to miss that extravaganza!
i don't really like my birthday anyways, so i'm gonna sick with the normal birthdays
10:03 Awesome, I'm taking psychedelics on that day.
"I'm 1,000 months old!" "Didn't your mother stop using months once you were two or three years old?"
Lol, my 500,000,000 second birthday is in nine days. Glad I watched this video, now I can celebrate it
Why are "half-birthdays" celebrated after six months, rather than 365/2=182.5 days or 366/2=183 days? For example, I was born on Dec 26 at 8:24 pm GMT, so my half-birthday should be June 27 at 8:24 am GMT, not the 26th. Stupid months not all having the same number of days..
I did it! I found all my math birthdays!! I had my 5000 days on my little brothers 8th birthday!! Wierd. I shared the link with all my friends so they don't miss theirs! 😉😊🎁🎁
This is easily one of the best videos on the Tubes of You.
7:26 You turn 30,000 weeks old when you're 574.9 years old. xD
My mum, dad and brother all have a prime birthday in two days. Party, I think so!
Maybe you could celebrate "angular" birthdays every time the earth covers one radian in its orbit... I just like to celebrate all the times I notice I'm actually enjoying myself.
Hey, it's my birthday today! I didn't even think that the title had birthday in it when I clicked on it! I think I'll change to prime birthdays tomorrow, just so I can keep this day
I actually do celebrate my birthday @ every 1,000 days ... it makes it a movable feast, and no-one but me knows when it is.
My 1347th prime birthday will be in 2 days. I'll be 11117 days old! Woo!! *waits patiently for ooodles of birthday cards*
Today is not my birthday! Hooray, I love to be part of the group with more probability to win!
This year I celebrated my first 'Astronomically Accurate Birthday" Astronomically Accurate? you say. I calculated the RA and Dec of Sun and Moon. This year , their value were the closest to the time when I was born.
Congratulations! Today's your 1521st prime birthday! You are 12743 days old. That's strange how I checked this video today without knowing. Next one is 12841.
I think hours may be off by a factor of 10.

Oddly enough, it actually is my birthday today. Albeit only a boring, normal one.
9:20 Isn't an irrational birthday impossible? Thanks to this video, I once told a friend that it was his "150'000 hours + 10* Pi^Pi days" birthday (I even told him the hour). But some days ago I realised that... it may be impossible! D: I mean, if you count a rational number of days, there are days before the exact moment, there is the day that contains that exact moment and there are days after your birthday. Obviously. You can count natural numbers, but also a decimal number of days, but the problem is the accuracy required by the amount of decimal positions: 4.5 days are exactly 4 days and 12 hours. 2.65 days are exactly 2 days, 15 hours and 36 minutes. 7.8064236(1) days are exactly 7 days, 19 hours, 21 minutes and 15 seconds. But you can't go smaller and smaller forever, because at a certain point you meet the Planck time, which is about 5.391E-44 seconds. For those who don't know, the "quantuum of time" is sort of a pixel of an image: you can't have a non-natural amount of pixels, it can't exist. So this means that for most of mathematical birthdays (almost everyone, like 99.99999...%) there actually is an exact moment (one (1.855E43)th of a second) which is your exact level up, but we generally aproximate it to the entire day that contains it. The problem here is that if you try to pick a non-integer amount of Planck times there will be two consecutive "Planck ticks": one before your aging and one after, but no one actually "during"! The problem is not only with irrational, but also with a very very small percentage of rational multiple of IS units.
I thought this was numberphile for a second, good stuff
Today's your 611th prime birthday! You are 4507 days old.
My 0.5 billionth seconds birthday is next Christmas Day
We should celebrate only Primary Psudo-Perfect Birthdays! I'm about to have the last one of my life, assuming that I don't live to the ripe old age of 1,806
alright boys first year without a prime birthday ready set go!
Today's my 1378th prime birthday! I'm 11423 days old...yay for me.
There are 8,760 hours in a standard year. I think these are supposed to be multiples of 100,000 hours.
the guy just needs more birthday gifts ... i understand
I totally celebrated my kiloweek (1,000 weeks) with an ice cream cake. That was nearly four years ago!
Hmm, according to you in the video, I should be somewhere between 22000 and 34000 hours hold, being 25 years, but according to the program linked in the description, I will be 250000 hours in 2021. Seems I'll have to program my own thing to calculate this ;P
I've just turned 59 and realise that I've just missed loads of excuses to party during my 50's. Looks like I'm going to have to wait until I'm 63 now. Bah!
7:18 i was really hoping that would be at 33 years it would have been so perfect
Well, what I celebrate on my birthday is that everyone I know gives me stuff for no real reason.
ever since mat's video about how many days there are in a year, I always use 365.2422 days/year in my calculations haha and when I'm lazy 75^4 seconds per year
That was such a fun video!!!
I celebrated my 1,000,000,000 birthsecond! It was a great - albeit *very* brief - party
Right over my head
today is my actual "orbits around the sun" birthday o.O
Has nobody noticed he said 11,987 days but wrote 11,981 in the Video? Be ashamed! :D great Video by the way!
Those hours are definitely way off. One year is already over 8,000 hours, and by the time you reach 91 you're almost 800,000 hours old. Adding an extra 0 to the number of hours makes it closer, but you're still always just a little bit low on the years.
57 What a year!
Is there any age when your prime number birthday is about as common as your traditional birthday? Also is there any traditional birthday (preferably before the age of 100) which is also a prime birthday? Finally, after all this, which year would you say is the most significant one? 57?
matt parker fan here, why am I discovering the channel only now ?? anyway... Parker First !
Hilarious, I really love this guy.
Holy shit. IT IS MY BIRTHDAY.
"Birthdays commemorating the earth orbiting the sun are boring. Lets celebrate the the earth rotating on it's axis instead.... but only count some of them."
I actually kind of celebrated my 1000 weeks "birthday".
What was that show where the guy celebrated his billionth second for one second?
I saw this video, just now. N found that tmrw is my 1071st prime bday. I will be 8599 days old.
brilliant! :D
My dad is really about this 10,000th days and 20,000th day birthdays =)
Once you’ve seen off the first billion seconds, you’ve seen off them all...
There's a mistake with your hour count. One passes one's 100.000 hour mark at 11, 200.000 at 22, etc. Not 10.000 and 20.000, as said in the video.
Dang it, i just missed my 1,000 weeks and 1,000,000 minutes!
So now, because I didn't celebrated any of these burst days, how many presents did I missed? ;(
What prime primes? The first, second, third, fifth, seventh, eleventh, etc primes. If you go by this measure, you would reduce your number of prime birthdays to a much more manageable amount.
At 7:30 Matt said "At 57 you will be celebrating 50,000 hours thats when you turned 30,000 weeks" Somehow I don't think that adds up...
Half a billion seconds old on the 18th of October 2016! Sometime early in the morning :3 Celebrate with me if you like
I got lost about 53 seconds into the video.
... I'm 57 for another 3 months ... all those milestones fotgotten ....
when I was a child I used to figure out how many seconds old I would be at a given time. as I post this I am approx 1041409800 sec old not only did I have to factor leap years but I was born 9 hours ahead of my current time zone
The average heartbeat of an healthy human is, according to the internet, between 90 and 180 bpm when a baby, from 80 to 100 as a child, 70 to 120 as a teenager and 60 to 90 as an adult. These have to be of course approximations because of both biological differences in people ageing at various rates and differences in lifestyles, but we can symbolically take a constant value of 135 bpm during the first two years, 90 bpm between 2 and 13 years, 95bpm from 13 to 20 and, finally, 75bpm after 20 years. We'll use a value of 365.2425 days as length of one year. I know these are just symbolic approximations of the actual values, but aren't regular birthdays too anyway? So, here are some notable heartbeat-based birthdays: 1 million beats = 5 days and 3 and a half hours 10 millions beats = 51 days and 10 and a half hours 50 millions beats = 36 weeks (8 and a half months) 100 millions beats = 1 year and 21 weeks 123456789 beats = 1 year and 38 weeks 200 millions beats = 3 years and 11 weeks 500 millions beats = 9 years and 29 weeks _6P(2)_ millions beats = 13 years and 48 weeks [*] 750 millions beats = 14 years and 38 weeks 1 billion beats = 19 years and 39 weeks 1.25 billions beats = 26 years and 1 week 1.5 billions beats = 32 years and 18 weeks Phi billions beats = 35 years and 18 weeks 1.75 billions beats = 38 years and 36 weeks 2 billions beats = 45 years and 1 week 2.25 billions beats = 51 years and 19 weeks 2.5 billions beats = 57 years and 37 weeks e billions beats = 63 years and 12 weeks 2.75 billions beats = 64 years and 2 weeks 3 billions beats = 70 years and 20 weeks Pi billions beats = 73 years and 50 weeks _12P(2)_ beats = 87 years and 2 weeks [*] 4 billions beats = 95 years and 38 weeks [*] Where _tP(n)_ means P(P(P(...P(n)...))) with a total of _t_ "P()"s, where _P(n)_ is the nth prime number. It's 3:30 AM and I'm here, under a five years old video, helping strangers to be annoying to their friends and relatives.
Matt- There's a goof in the 4th paragraph of the description below the video frame: One (average Julian) year (365¼ days) is 8766 hours. So 10,000 hours is barely over 1 year, not 11. You're missing a 0 in all your hour-birthday figures.
Seconds, minutes, hours and weeks are completely arbitrary time intervals. Base 10 counting system is also arbitary.

Weird that this video actually came out on my birthday.

Today is my 894th Prime Birthday! (Anyone who uses this to find out my birthday gets all my hearts
And it is my birthday!
Amazing.
127 days till my 1000th prime birthday!
You're right, Kalender-based Birthdays are rather arbitrary. But all every-day-life intervals of time are. What about interesting intervals of Planck Times?
Yay my orthodox birthday.

you forgot to put a zero behind te hour birthdays, when you are 11 you lived 100.000 hours, 200.000 @ 22 etc.
0:56 Shouldn't the graphic say 11,981?
whoo my 15th birthday is between a twin prime!!!
would be nice to have a year based list in description, considering how we look through the data. great vid though, thanks!
I don't celebrate birthdays, I celebrate approximate rotations survived.
"Ask your mum." --Matt Parker
I think I'll just celebrate twin prime days. I'll make it a 3 day event, so I'll start on the 1st prime, next day will be rest, then 2nd prime. That or just the days between the twin primes if I can't make it a 3 day event. I love twin primes. Sadly I don't know any off hand and I missed many of them. Good thing about prime birthdays, you will never run out, so 1 billion years later you will still have a prime birthday, but with today's technology I'm not sure if we can point out the exact days.
I cannot know exactly for 1 billion seconds -- my birth time is recorded in date, hour and minute. No second. Think of the labour.
missed most if not all of the "important" ones already :(
My computer's running terrably slowly meaning i can't check all the comments first [and google plus's messing doesn't help] so I'm sorry if someone has already pointed this out, but the number of repeated errors that slipped through is/are simply stunning. I intend this more as a corection than a complaint. There is nothing wrong with the numbers, so to speak. The error seems to be less with the maths, and more with the order of magnitude. I'll just start by clarifying that the value of 1 billion was used as 10^9 [or at least to be right, it would need to be]. Off we go then. The number of hours [eg 50,000 hours at 57 years] is a power of 10 too low [57 (years) x 365 (days) x 24 (hours) = 499,320 - or approximately - 500,000 hours]. Also, whilst talking about hours Mark says that at 57 you passed 30,000 weeks [not strictly speaking a mathematical error, he got it right first time, but I was puzzled at how 3x7x24 =5 not =504 (that's out by one power of 10 for the 30,000 slip, and one for the 50,000 hour error) which is why I checked the other numbers]. Lastly, while the billion second calculations are correct, the quoted 5 million minutes as aproximatly 3 billion seconds is wrong it should be 50 million minutes [5x10^6 x 6x10^1 = 30x10^7 = 3x10^8 not 3x10^9 as it is claimed to and as 5x10^7 x 6x10^1 does] I hope this clears things up more than it confuses, although looking back I'm not sure.
10,000 hours is ~416.66 days
