| Year | Odd Days |
| 100 | 5 odd days |
| 200 | 3 odd days |
| 300 | 1 odd days |
| 400 | 0 odd days |
Now,
Till 1932 → 1600 + 300 + 32
| Leap Year | 2 Odd days |
| Ordinary Year |
1 Odd day |
In 1600 Years the odd day is 0,
In 300 Years the odd day is 1,
In 32 Years(8 Leap Years and 24 Ordinary year) the odd day is 8 × 2 + 24 × 1 = 16 + 24 = 40 odd days,
⇒ 0 + 1 + 40
⇒ 41 odd days.
And, from 1st Jan 1933 to 23 March 1933:
⇒ 31(Jan) + 28(Feb, 1933 is not a leap year) + 23(March) = 82 days.
Total odd days → 41 + 82 = 123 days = 123/7 = 17 weeks and 4 odd days.
→ 4 represents Thursday.
So, 23 March 1933 is Thursday.
Hence, the correct answer is "Thursday".
