Thank you for remindig me of newspaper archives. Should have thought of it myself. I spent 6 Euros to buy two archive copies of Il Messagero, a Roman paper, for 1 and 2 April 1944. The edition of 2 April has this note: Tonight at 2 am, put forward the clock by one hour. Remember that in the night between today and Monday the 'ora legale' will come in force again. That makes it clear that in Rome the change was on Monday, 3 April 1944 at 2 am. Screenshot of paper archive attached. On 02.07.19 02:42, Paul Eggert wrote:
Of course primary sources (such as Roman newspapers during that period) would be better than my guess, but it was a chaotic time and it might be difficult to come up with anything reliable.
