Date my guitar

No, not like that, although it is very pretty.

I have a very un-glamorous sounding ESP LTD XTone Paramount Series PC-1V here, the serial number is S0700605.

As I understand it, this means it was year 07, week 00, day 6, 5th guitar of the day.

What is the 'zero'th week?

---------- From 2000 to 2015 ----------

8 DIGITS stamped in the back of the headstock:

PPYYWWDNN (stamped on the back of the headstock).
PP = place of manufacture:

K = ESP Kiso Factory (Japan) / set-neck and neck-thru only;

S = ESP Sado Factory (Japan) / bolt-on only;

T = ESP Takada Factory (Japan) / ESP Custom Shop

SS = ESP Standard Factory / Signature Series or Standard Series

CH = Craft House

CS = Craft House (used rarely)

TH = Technical House

N = Nagano Factory

YY = last two digits of the year
WW = week of the year (max.52)
D = day of that week: 1 = monday, 2 = tuesday,... (max.7)
NN = number off the line that day (max.99)
EXAMPLE: the code of my MX-250 K0604202 means the manufacturing date is 24.01.2006 and it was the 2nd guitar built that day.

If I type the serial number in here:

https://www.guitarinsite.nl/serienummers-esp_eng.php

It says:

Serial number: S0700605

Production year: January 30, 2007
Production number: 05

Made in Japan, custom shop Sado. [bolt-on]

Seem like a silly/trivial thing, but my 5 year old Nephew wanted to know when it's birthday is, and how old it'll be. Anyone good with understanding these serial numbers? Thanks.

Is the serial number stamped into the headstock wood or a decal under the clear top coats of the finish?

There are ways that either method could go awry at the turn of the year.

I  thought this was going to be a advert for the latest TV reality show.

If January 30th is the 00 week must be using the Chinese calendar
