Pick a calender, any calender

[Fiddlers Green]

A slightly modified Persian Solar Calendar.
Modified in that it's based from my current location, rather than the Persian (Iranian) capital (Tehran).
The version we use is more in line with the Achaemenian and, to a lesser extent, Yazdgerdi calendars, rather than the Lunar version the Muslims forced on Persia, and the later reconstruction under the Pahlavi Dynasty.
We do keep some portions of Pahlavi's reconstruction, but reject the standardization of days in a month, rather, basing the years start point from the Vernal Equinox and is event based, rather than numericly based.
Meaning, the Vernal Equinox is always the first day of Farvardeen (rough transliteration).

Secular is focused on the US. Standard. Religious observiences depend upon the holiday in question.

you just reminded me I don't have 2007 calendar.

I usually use Gregorian, and then convert to Discordian when I have the time.

I find it amusing. My family almost always buys calenders as Christmas gifts. I usually end up with three from three different sides of my family. And I always end up getting another one because no matter how many times I tell them what I want, no one ever buys the correct one for me.
