Pa. Const. sched. 2, § 1

That no inconvenience may arise from the changes in the Constitution of the Commonwealth, and in order to carry the same into complete operation, it is hereby declared that--

In the case of officers elected by the people, all terms of office fixed by act of Assembly at an odd number of years shall each be lengthened one year, but the Legislature may change the length of the term, provided the terms for which such officers are elected shall always be for an even number of years.

The above extension of official terms shall not affect officers elected at the general election of one thousand nine hundred and eight; nor any city, ward, borough, township, or election division officers, whose terms of office, under existing law, end in the year one thousand nine hundred and ten.

In the year one thousand nine hundred and ten the municipal election shall be held on the third Tuesday of February as heretofore; but all officers chosen at that election to an office the regular term of which is two years, and also all election officers and assessors chosen at that election, shall serve until the first Monday of December in the year one thousand nine hundred and eleven. All officers chosen at that election to offices the term of which is now four years, or is made four years by the operation of these amendments or this schedule, shall serve until the first Monday of December in the year one thousand nine hundred and thirteen. All justices of the peace, magistrates, and aldermen, chosen at that election, shall serve until the first Monday of December in the year one thousand nine hundred and fifteen. After the year nineteen hundred and ten, and until the Legislature shall otherwise provide, all terms of city, ward, borough, township, and election division officers shall begin on the first Monday of December in an odd-numbered year.

All city, ward, borough, and township officers holding office at the date of the approval of these amendments, whose terms of office may end in the year one thousand nine hundred and eleven, shall continue to hold their offices until the first Monday of December of that year.

All judges of the courts for the several judicial districts, and also all county officers, holding office at the date of the approval of these amendments, whose terms of office may end in the year one thousand nine hundred and eleven, shall continue to hold their offices until the first Monday of January, one thousand nine hundred and twelve.
