The following table presents shares used in the calculation of basic and diluted net income per share:
| Three Months Ended |  |  | Six Months Ended |
| March 31, |  |  | March 31, |
| 2020 |  |  | 2021 |  |  | 2020 |  |  | 2021 |
Weighted average common shares outstanding used in calculating basic income per share |  | 21,520,215 |  |  |  | 22,143,043 |  |  |  | 21,486,995 |  |  |  | 22,083,827 |
Effect of dilutive options and non-vested restricted stock awards |  | 440,070 |  |  |  | 843,018 |  |  |  | 438,110 |  |  |  | 781,123 |
Weighted average common and common equivalent shares used in calculating diluted income per share |  | 21,960,285 |  |  |  | 22,986,061 |  |  |  | 21,925,105 |  |  |  | 22,864,950 |
For the three months ended March 31, 2020 and 2021, there were 21,333 and no weighted average shares of options outstanding, respectively, that were not included in the computation of diluted income per share because the options’ exercise prices were greater than the average market price of our common stock, and therefore, their effect would be anti-dilutive. For the six months ended March 31, 2020 and 2021, there were 21,333 and 104 weighted average shares of options outstanding, respectively, that were not included in the computation of diluted income per share because the options’ exercise prices were greater than the average market price of our common stock, and therefore, their effect would be anti-dilutive.
