Today, Monday 4th August 2024, being the first Monday in August, is a Bank Holiday in Ireland. This holiday was created by the Bank Holiday Act of 1871 when Ireland was under British rule. While the August Bank holiday was subsequently moved to the end of August in England and Wales, it has remained at the start of August in Ireland.

We have had some proper Bank Holiday weather, in the form of Storm Floris. Although the worst of this passed to the West of Maynooth, the winds were powerful enough to blow one of my wheelie bins over.

As I mentioned last week, the first day of August marks the old pagan festival of Lughnasadh, named after the God Lugh, on which is celebrated the beginning of the harvest season. This coincides with the English Lammas Day, one of many Christian festivals with pagan origins. Traditionally this is the start of the harvest season and is celebrated accordingly, with rites involving the first fruit and bread baked from flour obtained from the first corn. It is also one of the cross-quarter days, lying roughly half-way between the Summer Solstice and the Autumnal Equinox (in the Northern Hemisphere).

I’m reminded that this time last year I was still on sabbatical. That seems like ages ago. When I resumed teaching last September I had to teach two modules I’d never taught before: a fourth-year Mathematical physics course on Differential Equations and Complex Analysis and a second-year Engineering Mathematics course. This time should be a bit easier as I get to do both of these again. Over the year I also had a final-year undergraduate project student and an MSc student. Both have been a pleasure to work with. The Masters course lasts a calendar year so that one isn’t quite finished, but the deadline for handing in their dissertation is close, next Monday (11th) in fact.

After I return to work tomorrow the next big item on the agenda is the repeat examination period, which starts on Wednesday August 6th. The fates have conspired to require me to be “on call” for four papers next Saturday (two of my own and two covering for a colleague): three of these are scheduled at 12.30 and the other one at 15.30 so I’l have to be by the phone all afternoon in case any matters arise. I also have three others scattered through the approximately ten days of the examination period.

After the repeat examinations are done, the marks uploaded, and the Examination Board has done its work, the next job will be to prepare for the new intake of students. This year’s Leaving Certificate results will be announced on Friday 22nd August, at which point we’ll see how many students (if any) we have studying Physics next academic year which, if all goes to plan, will be my antepenultimate…

Today, Monday 5th August 2024, being the first Monday in August, is a Bank Holiday in Ireland. This holiday was created by the Bank Holiday Act of 1871 when Ireland was under British rule. While the August Bank holiday was subsequently moved to the end of August in England and Wales, it has remained at the start of August in Ireland. Today is also a Bank Holiday in Scotland, though the Scots have the best of both worlds and have a holiday at the end of August too.

The first day of August marks the old pagan festival of Lughnasadh, named after the God Lugh, on which is celebrated the beginning of the harvest season. This coincides with the English Lammas Day one of many Christian festivals with pagan origins. Traditionally this marks the start of the harvest season and is celebrated accordingly, with rites involving the first fruit and bread baked from flour obtained from the first corn. It is also one of the cross-quarter days, lying roughly half-way between the Summer Solstice and the Autumnal Equinox (in the Northern Hemisphere).

It seems to be a tradition in Maynooth that the Bank Holidays in May and August are are adjacent to examinations. This year they start on Wednesday (7th August). I am, however, still on sabbatical so I don’t have any correcting duties. That doesn’t mean I can’t wish all the students taking repeat examinations all the best in their endeavours.

This month is the last of my sabbatical. I officially return to normal duties on 1st September, but that is a Sunday so I won’t return to the office until Monday 2nd September. That is if I have an office. There’s a lot of reorganization going on and currently I don’t know where I’ll be based. At least I know what I’ll be teaching in Semester 1 though: a fourth-year Mathematical physics course on Differential Equations and Complex Analysis and a second-year Engineering Mathematics course. These are not what I would have chosen if I had a free hand (I’d rather teach physics than mathematical methods) but I’ve had it excessively easy for the last year so can’t complain. With a bit of luck I might get a project student or two as well, if the students haven’t forgotten who I am!

Today, Monday 7th August 2023, being the first Monday in August, is a Bank Holiday in Ireland. This holiday was created by the Bank Holiday Act of 1871 when Ireland was under British rule. While the August Bank holiday was subsequently moved to the end of August in England and Wales, it has remained at the start of August in Ireland. Today is also a Bank Holiday in Scotland, though the Scots have the best of both worlds and have a holiday at the end of August too.

I recently mentioned that 1st August marks the old Celtic festival of Lughnasadh, named after the God Lugh, on which is celebrated the beginning of the harvest season. This coincides with the English Lammas Day one of many Christian festivals with pagan origins. Traditionally this marks the start of the harvest season and is celebrated accordingly, with rites involving the first fruit and bread baked from flour obtained from the first corn. It is also one of the cross-quarter days, lying roughly half-way between the Summer Solstice and the Autumnal Equinox (in the Northern Hemisphere).

In the Northern hemisphere, from an astronomical point of view, the solar year is defined by the two solstices (summer, around June 21st and winter, around December 21st) and the equinoxes (spring, around March 21st, and Autumn, around September 21st). These four events divide the year into four roughly equal parts of about 13 weeks each.

Now, if you divide each of these intervals in two you divide the year into eight pieces of six and a bit weeks each. The dates midway between the astronomical events mentioned above are (roughly) :

  • 1st February: Imbolc (Candlemas)
  • 1st May: Beltane (Mayday)
  • 1st August: Lughnasadh (Lammas)
  • 1st November: Samhain (All Saints Day)

The names I’ve added are taken from the Celtic/neo-Pagan (and Christian terms) for these cross-quarter days. These timings are rough because the dates of the equinoxes and solstices vary from year to year. Imbolc is often taken to be the 2nd of February (Groundhog Day) and Samhain is sometimes taken to be October 31st, Halloween. But hopefully you get the point.

It seems to be a tradition in Maynooth that the Bank Holidays in May and August are are adjacent to examinations. This year the repeat examinations began on 1st August. My first paper (of four) was on Saturday and I have two more on Tuesday (tomorrow). That means by the end of tomorrow I will have three packets of scripts to mark…

There are two ways of looking at the fact that the day before these exams is a holiday. One is that students have an extra day to revise. Another is that the holiday is ruined by having to prepare for examinations.

Anyway, by the time the Solstice arrives I will hopefully away on sabbatical.
