Ex-miners will next week mark the 20 years since their pit closed, with a party in Easington in County Durham - on the day of Baroness Thatcher's funeral.
Alan Cummings, chairman of the Durham Miners' Association, said the timing of events was "remarkable" and "one of those quirks", though he added:
"She couldn't be cremated on a better day."

The party will be held on Wednesday at the Easington Colliery Club, in the former pit village, subject to the committee's approval, he said.
On Tuesday evening there will be another party for the women's groups who supported the striking miners, he said.
"We are planning to have a colliery band and we are inviting ex-miners and their families to go back over their memories of the strike and what has happened since the closure of the pit."

The pit in Easington Colliery, which was the setting for the film Billy Elliott, closed in 1993, with the loss of 1400 jobs and it is one of the most deprived parts of the country.
Mr Cummings, an ex-NUM Lodge secretary, said the event was not in poor taste and he had only received positive feedback.
"I couldn't stand her.
"She had a very patronising manner and I could have put my foot through the television whenever I saw her on there.
"We opposed and hated everything she did. She has wrecked thousands and thousands of lives so, no, it's not in poor taste.
"We can understand why people are happy and rejoicing that she has gone because they remember these communities have never recovered."

Many people who live in the area where the potash mine could be built say that they are worried that, if built, it could spoil one of England's most beautiful areas.

Proposals for a new potash mine south of Whitby have come a step closer as planning documents have been submitted to the North Yorkshire Moors' National Park Authority.
The plans for the mine four kilometres south of Whitby would create thousands of jobs.
However, opponents claim that the potash mines would be a blot on the landscape.
A major planning battle is expected after a mining company announced today it had submitted a long-awaited application to sink a potash mine in the North York Moors national park, creating a 1,000 permanent jobs.
Sirius Minerals wants to build the mine two-and-a-half miles south of Whitby. It says the mine would exploit what is believed to be the world's biggest and best quality supply of potash, which is used to make fertiliser.
But critics say the technology is untested and the mine will be an eyesore in the heart of one of the region's most protected landscapes. The company says it expects a decision to be made by the national park planning authority in May.
"This is a major milestone for the company and one that we believe brings us closer to the first day of construction and production at the York Potash Project."
