Principles of calculation.
Civil law is civil law. Calculation of the month. If you set the duration in months, add the number of months of service to the entry date. The day before the month.For example, if you join the army on 1 February 2026, add 18 months to the day before 1 August 2027, i.e. 31 July 2027This transition is scheduled.
According to 2026, the period of military duty and examples are as follows.
| Tagged as | service time | February 1, 2026. |
|---|---|---|
| Army | 18 months | 31 July 2027 |
| The Marines | 18 months | 31 July 2027 |
| Tagged office | 18 months | 31 July 2027 |
| Navy is | 20 months | 30 September 2027 |
| army | 21 months | 31 October 2027 |
| Social service officer | 21 months | 31 October 2027 |
If there is no same date in the additional month, adjust it to the last day of the month. For example, as the first month of the entry date of January 31 does not exist, February 31 is calculated as the end of February (28th of the year, 29th of the year) and the overall scheduled date applies to the previous day there. The progress rate of service is calculated as the ratio of the previous number of scheduled days from the entry date to the date of the entry date to today (circular days ÷ full days × 100) and is displayed in the range from 0 to 100%.
