Legal time limit problem

Landlord, in fact, their statements are consistent. Let me quote again for your understanding. Article 6 of the Detailed Rules for the Implementation of the Patent Law stipulates that if the time limit is calculated in years or months, the corresponding day of the last month shall be the expiration date of the time limit. Article 103 stipulates that the time limit calculated in months is one month from the date of this month to the date of next month. For example, the probation period from this month 1 to the next month 1 and from the last day of this month to the last day of the next month is one month. For example, the implementation opinion of Article 198 of the General Principles of the Civil Law stipulates that the period agreed by the parties shall not be counted from the first day of the month or year, with a month of 30 days and a year of 365 days. It means that no matter whether a month is a leap month or not, as long as it is a month, every month counts as 30 days. In other words, the signing date of the contract is the 28th of this month, about one month, so the expiration date is the 28th of next month. If it is about half a month, it is 15 days. If you make an appointment by the day, then count by the day, otherwise it is not a specific number of days. So in this case, the three statements are actually the same.
