Guys,

Now that you've started compiling historical information from Diqiu, I've been asked a couple of times by different archivists and researchers for information on reckoning Standard dates from the ones found on local-origin documents. Rather than keep sending out the same email, I figured it would be more efficient to send you all over this handy cut-out-'n-keep guide.

The conversion is actually really simple. The Diqiu calendar is the Standard calendar, they just have different names for the months and the days of the week, and they reckon their zero year differently. (James presumes this is another example of transtemporal echo, like the similarly parallel Cephirean calendar.)

There are a few odd variations when you start getting into earlier recorded history ("recorded history" in Diqiu goes back something like 10,000 years), but for almost any practical purpose you're likely to encounter, this chart works perfectly well. Any other questions, just let me know.

Mahalo,
--G.
