Reference for Saints' days, Easter Tables and regnal years: C. R. Cheney, Handbook of Dates for Students of English History (Royal Historical Society, any edition). The following discussion examines how to use the sections of Cheney sequentially to find the precise date.


1 In the table of saints' days, Michaelmas is immoveable at 29 Sept. Cheney, Handbook, p. 56 

2 The regnal year 9 Edward III ran from 25 Jan. 133524 Jan. 1336. Cheney, Handbook, p. 20. Therefore this Michaelmas fell in 1335. 

3 The Easter Tables specify that in 1335 Easter fell on 16 April. Cheney, Handbook, p. 158 

4 The calendar for the year in which Easter fell on 16 April
reveals that Michaelmas fell on Friday in that year, so the Tuesday
before was the 26th Sept. [1335]. Cheney, Handbook, pp.1345.
