Well...prepare yourself for a long read.

We're going to start remarking the fact the series is based on real time. Why? Because in Nightmare Hospital Connie said to her mom "I haven't needed the glasses for almost a year!", making a reference to the events of An Indirect Kiss. Now, air dates of said episodes were Sep 10th, 2015 and Sep 18th, 2014 (almost a year of difference).

With that in mind, let's move on Peridot. In Back to the Barn she says to Pearl in their discussion "I'm a natural technician and a certified kindergartener. I was made for this! (referring to the drill construction)". Now, I want to point two facts on this sentence.
 * She indeed have to get a certification (some form to guarantee she's not defective).
 * We can just assume this certification had a short enough amount of time.

Furthermore, we know the dates of the logs are one day long (since we seen Peridot repeating "Log date 7112" throughout that day). This is important, because this gives us the age of Peridot (7111 log dates old + the time she was being certified).

With that on mind, we have to see what is the length for a day on Homeworld. For that, we'll move to Warp Tour. In said episode, Peridot states it's the day 312 (as she says "Log date 312" when arrived to the Earth).

Now, since a log date is a day old, we need to state Peridot's been in 2 different planets, and the log dates have different lengths as well. She arrived to Earth on The Return, that means, she's been there 217 days. 7112 - 217 = 6895, 6895 - 312 = 6583.

Finally, we check the date Warp Tour was released (january 8, 2015) that means 6583 logs dates (homeworld days) passed in 61 days, which means a Homeworld day is 61/6583 Earth days (the decimal is way too long to put here). We need this value to calculate how long 312 logs take, and we have it takes around 3 Earth days.

Now, with all this data, we can estimate the date Peridot was created as Jan 7, 2015.

So that's it. Peridot is almost a year old at this point.
