Give the event date start and a period (15d, 2w, 3m, 1y, 1y6m, 10wd for working days, or "30 ngày", "3 tháng") or a rule id from the built-in table, and the API returns the last day of the time limit following the Civil Code 2015: the event day is not counted (art. 147), months and years end on the corresponding day (the last day of the month when there is none), and a period ending on a weekend or public holiday ends on the next working day (art. 148(5)), using the official Vietnamese holiday schedule. mode=fixed counts a month as 30 days and a year as 365 days (art. 146), suspended_days adds time not counted in a limitation period (art. 156).
Without start, the API lists the table: limitation periods for contract and tort claims (3 years), inheritance (30 / 10 / 3 years), void transactions, commercial disputes (2 years), labour disputes (6 / 9 / 12 months), administrative complaints (90 days) and lawsuits (1 year), appeal periods (15 days, 7 days), cassation protest (3 years), enforcement requests (5 years)… each with its article. Filter with category or q. format=ics returns a calendar file with reminders.
The response explains each step and cites the articles. It is a reference: check how the specific law counts the period.

FAQ
Does the period start on the day of the event?
No. Under art. 147 the first day is not counted; the period starts the next day. A 15-day appeal period from a judgment pronounced on 15 April ends on 30 April, moved to the next working day when that is a holiday.
What if the last day is a holiday?
The period ends at the end of the next working day (art. 148(5)). Holidays come from the official schedules announced for civil servants.
Which law sets the limitation periods?
Each rule cites its law: Civil Code, Labour Code 2019, Law on Complaints, Civil / Criminal / Administrative Procedure Codes, Law on Civil Judgment Enforcement 2025.
