He had served as a lay steward at St George’s Chapel, secretary of the Friends of the Chapel and had helped to organise exhibitions marking the Duke of Edinburgh’s 90th birthday and anniversaries of the Queen’s accession and Coronation.Profiled in the New York Times in his 40th year of record-keeping, Mr O’Donovan described how he had started “my tables” as a hobby, cutting out the Court Circular from his newspaper and pasting it into a ledger before keeping a running total.”It was just a fascination with what they actually did,” he said. “Some of them work extremely hard.”One has had a huge amount of enjoyment out of doing it, because one has met people one would never have met before. It has widened one’s life, in a way.” “All engagements differ as to time and content and there is also the time taken in preparation to consider, whether it be a visit, investiture or speech.”In 2018, the Princess Royal undertook 518 public engagement, the Prince of Wales 507 and the Queen 283, while the Duke of Cambridge managed 220 and Duke of Sussex 193. The Duchess of Cambridge did 87, reflecting her time on maternity leave, whilt the Duchess of Sussex who joined the family in May managed 96. “All I’m doing is recording their activities,” he said. “It’s just a straightforward table of events, really.”Mr Donovan, who does not know who – if anyone – will take over his record-keeping when he dies, has promised to continue “as long as I can write and use a pair of scissors”.He remains a great admirer of the Queen, who will celebrate her 93rd birthday in April.”I think we have been amazingly lucky to have such a wonderful monarch,” he told the newspaper.”Continuity is a great thing, and I think there has never been any question of impropriety, like there are among other heads of state around the world. She has had an unblemished record.” Tim O’Donovan’s ledgerCredit:Mary Turner/NYT A photograph of the Queen speaking to Tim O’Donovan, third from rightCredit:Mary Turner/NYT Mr O’Donovan also appears to have won over any doubters at the palace. In 2016, he was among 180 pensioners invited to the chapel to receive Maundy money from the Queen in recognition of their service to church and community.

Relaying how he had visited the Queen’s private secretary in the early 1980s to reassuring them of his good intentions, he said: “I suppose one was anxious because one did not want to stop doing it.””If they had said, ‘Mr. O’Donovan, we don’t want you to go on doing this,’ I would have obeyed them.”He now accompanies the published version with a caveat which last year read: “I should, of course, emphasise that the table of figures below should not be converted into a “league table” of individual royal performance.
