This Blog is Closing Down

April 14th, 2020

I regret to advise that this blog will soon be closing down, as I don’t tend to keep it updated any more, so there’s not really much point in keeping it any longer as it uses up space on the server.

However, as there are some popular files stored here, these will still be available. They will be located at the following address:

https://time-meddler.co.uk/calendars

Note that the blog may come back at some point, but with an entire site redesign, if that works out. Otherwise, everything will be accessed from the main Time Meddler’s Calendarium home page going forward.

Happy Easter!

March 21st, 2019

Well, in my reckoning it is Easter at any rate – it’s the churches that have got it wrong. Even their own rule states that Easter should be the first Sunday after the first full moon on or after the northern spring equinox, which is taken as being the fixed date of the 21st March. And the full moon is today, the 21st March, so Easter should be this Sunday, the 24th March.

However, the churches don’t use the actual date of the full moon and instead use a calculation called Computus to work out when the Easter full moon occurs, and this obviously puts the date of this particular full moon as the 20th March. Consequently, by this method of calculation, the Easter full moon is instead deemed to be the one that occurs on 19th April, thus pushing Easter back to Sunday the 21st April this year.

My calendar, however, follows the moon and the seasons, and today’s full moon is the first one following the northern spring equinox, which occurred yesterday. And even my own version of computus puts the date of the full moon as the 21st March, so today’s full moon is my Easter Full Moon, or Ostara, or the Egg Moon. So, Happy Easter from me. Cheers!

New Calendar System

January 6th, 2019

I am in the process of changing to a new reckoning for the calendars. The months will be the same and will occur in the same order and place as originally intended. What will change is the length of each month, i.e. whereas up to now odd-numbered months had 30 days and even-numbered months had 29 days in most cases, in the new reckoning any month can have either 29 or 30 days, depending one where they fall in the longer cycle that determines how many days are in each month.

In the current cycle the months will have the same number of days as usual until Siùfainn, which will have 30 days instead of the usual 29, and subsequent months will be switched until the next occasion that there are two months in a row with 30 days. However, the start dates of the months in the current cycle are also currently a day earlier than in the original system, e.g. Dumhainn began on 9th December 2018 in the original system but in the new system it began on the 8th December.

I will be changing the date widgets in the sidebar to the new dates, and for the next year I will post the calendars in the old system and in the new. The new versions for the months so far this year are available at the following links:

Happy Yule

December 21st, 2018


  13 Dumhainn, 3045       165·1·2·13       1 Aeftergiuli, 1575  
Today is the day of the Winter Solstice in the Uk and in my notional Old English calendar it is the 1st of Afteryule, which begins the year of 1575 in that calendar. This year is a leap year as there are 366 days between Winter Solstices in UTC time reckoning. This is marked by the addition of an extra day to the second month (Solmonath), making it 30 days long instead of he usual 29.

The calendar for the year 1575 in the Old English calendar can be downloaded at the following link: Old English Calendar 1575.
