Errors of the Past

When looking back at previous determinations, there is concern as to their accuracy. The lunar month, and in turn Ramadan, is either 29 or 30 days. As previously mentioned, it’s not impossible for Ramadan to have the same number of days in two consecutive years. However, it’s very unlikely for Ramadan to have the same number of days for three or more consecutive years.

What one would expect when looking retrospectively over say the  5 Ramadans from 2019 to 2023, is a somewhat even distribution of 29 and 30-day months. This means looking at that 5 year period, one would expect Ramadan to have been 29 days on 2 or 3 years and 30 days on the other 2 or 3 years. For the 5 consecutive Ramadans during that period, ANIC determined Ramadan to be 30 days. This strongly suggests error. The dates are found below.
