Sections 12-24 explain how limitation periods are calculated and what exceptions apply under the Limitation Act of 1963. Section 12 eliminates the time required to receive certified copies of judgements, decrees, or orders, as well as the date the judgement is pronounced. Section 13 excludes the time spent on legitimate applications to sue or appeal as an indigent person if rejected. Section 14 excludes time spent litigating in a court without jurisdiction, assuming it was done in good faith. Section 15 eliminates those periods during which proceedings were delayed due to injunctions, statutory notifications, mandatory approvals, insolvency, winding-up, or the defendant’s absence from India.

Section 16 states that if a party dies before the right accrues, the limitation begins when legal representatives can act, with the exception of pre-emption or hereditary claims. Section 17 suspends limitation in circumstances of fraud, error, or concealment until discovery. Sections 18 and 19 restart the limitation period if a written acknowledgement of debt or partial payment is made before the expiration date. Section 20 binds represented persons if acknowledged or paid by a guardian or manager, but not all joint debtors. Section 21 handles the addition of new parties, Section 22 deals with continuous breaches, Section 23 links limitation to the occurrence of damage, and Section 24 requires calculation using the Gregorian calendar.
