This post is about me doing shit stuff.

Not wasting any time in explaining the reason of 420, instead, we will treat 420 as just a time of day as our interesting phenomenon and do soe analysis based on it.

## Four

Inspiration : Check out this link

Green parts are lit.

## Two

Every country has it’s own timezone or timezones. Although, the definition of the timezones, meaning the Longitude a country may choose which in turn sets the time for the whole country need not be unique to the country. This would mean that geopolitical boundaries are not unique in the sense that two boundaries can have same time but different timezones.

An example (which I wasn’t aware of):

• Timezones Asia/Kolkata and Asia/Colombo have the same time but for all timezones purposes they’re considered different. Hence, for the purpose of this study we have to merge all such regions together.

#### How do I do it?

I make use of pytz and datetime to handle all my datetime conversions across all timezones. This part was easy. I had to prepare a lot of sacrifices to actually plot. I’ll be frank, it was a big pain in the ass. Firstly, I didn’t know shit how to do that. I couldn’t take country boundaries. So, I searched online and found this timezone-boundary-builder and then I got hold of the shapefiles and many Googles later, I came across Shapely GeoPandas and Cartopy. And, the result is the plot.

I will put the scripts in my randomshit repo on my Github. Look out for 420 commit.

#### Per minute analysis

In an ideal setting, there should be a lit timezone every minute, meaning the lit timezones should be distributed uniformly and completely across the day.

We note that it is not the case.

### dank facts

• There are $$432$$ timezones considered in this study. - Of the $$432$$ timezones, theoretical lits that can happen in a single day is $$864$$, which is nothing but twice the number of timezones.
• Max. number of simultaneous lits is $$57$$.
• Min. duration between lits is 15 minutes.

## Zero

The effect of Daylight Savings.

At the end of the previous section, we noted a fun fact that max. number of simultaneous lit timezones is $$57$$.

Now, something I learnt which will be duly investigated in this section is: Daylight Savings end in US/Central one week before it ends in Mexico. So, this means, there is at least one more 420 happening. Sooooooooooooooooo, I re-did the script to do something like this:

It takes a lot of time and the result is.

We note the following after observing the above plot:

Day of year # lits -864 Nature MM/DD
68 +8 Max. 03/10
79 +1 Max. 03/21
263 -1 Min. 09/21
306 -8 Min. 11/03

The # lits is symmetric with $$+8,+1,-1,-8$$. But, day of year is not symmetric, $$79 - 68 != 306-263$$.

Timezones get more lit. They having party.
