Which calendar should I celebrate my birthday, lunar or solar?

Depends on where you were born and what calendar was used then?

The Gregorian is corrected for seasons and movement of the Sun.

Lunar calendars are all wildly inaccurate, and don’t reflect a year’s passage or the comings and goings of the seasons.

Both. I’m all for doubling parties.

I’ve never kept up with the lunar calendar, so I have limited experience. Seems I remember that the lunar calendar can be off as much as a day depending on your location. I think I’d celebrate in both April & June; however, I’d only become a year older in May!!!

Both.

Julian.

That way, it’ll be the same day whether you use a lunar or a solar calendar.

@Brian1946 The Julian calendar is not a lunar calendar, it is just inaccurate over a long period of time.

@LadyMarissa the lunar calendar can be off as much as three weeks year over year, and longer over a number of years. The Hebrew calendar throws in a leap month every few years to correct itself.

The Islamic calendar is off by 11 or 12 days a year. That is why the important holidays are not consistently in the same season.

And yet, some people think time is an element, that time can be traveled, or that time can stand still.
That time can’t even be accurately counted, should be enough to show everyone that time is a manmade concept. Time is nothing more than a means of tracking the movement Vs nonmovement of events.
I didn’t want to embarrass the man while he was alive, but Stephen Hawking chose as his area of study something no more mysterious than written language.
What he might have endeavored to prove is whether any specific ongoing event coincides perfectly with any other long term ongoing event, so that the base movement of those events could be used to mark time fore humans.
We count time in relation to events of our planet, our moon, and our sun. There is bound to be a more reliable event we could use so consistency could be found.
Currently, seconds are counted according to a fraction of an inconsistent set of events.

Sorry Mr. Hawking, it had to be said.
