Elmo Smith, the relator, is the 1960 primary election nominee of the Republican party for the office of United States Senator. On August 30, 1960, he tendered to the Secretary of State his statement and picture for printing in the “General Election Pamphlet,” an election document described in ORS 255.211. The Secretary of State, acting on the advice of the Attorney General, refused to accept it. He contends that it was not filed within the time fixed by that section of the code; that is, that a filing on August thirtieth did not comply with the requirement that the statement must be filed- “not less than 70 days before the * * * general election,” which is November 8, 1960. Thereafter, relator filed his petition in this court for a writ of mandamus to compel the Secretary of State to accept and file relator’s tendered material and thereafter include the same in the Voters’ Pamphlet. The Secretary of State demurred to the ensuing alternative writ on the ground that it did not *578state facts sufficient to constitute a cause for mandamus against the defendant.
The sole issue is whether relator made a timely tender. Both parties agree that August thirtieth was the seventieth day before the election. Both attain that result by excluding November eighth, the election day, and including November seventh as the first day of the backward count and concluding with August thirtieth as the seventieth day. The relator contends that a filing on the seventieth day complies with- the statute. The defendant contends that a filing on the seventieth day does not comply—that 70 full or clear days must intervene between the filing and the election ; in other words, that the filing must be made on the seventy-first day. He argues that August twenty-ninth, or the seventy-first day, is the last day upon which filings could be accepted.
Both parties invoke ORS 174.120 as the controlling statute for justifying their respective computations. The defendant relies particularly upon State ex rel Stewart v. Macy, 82 Or 81, 161 P 111 (1916), in support.
ORS 174.120 in substantially its present form has been a part of the law of this state from 1864 to 1949. It was then amended for the first time (Oregon Laws 1949, eh 287, p 411). Prior to 1949 and thereafter and until 1953, it in fact comprehended two rules. The first sentence or first rule related to the computation of time “within which an act is to be done.” The second and only additional sentence or second rule related to the computation of time for the publication of legal notices. Later, by reason of the provisions of Oregon Laws 1953, ch 3, p 20, revising the statute laws of Oregon, each rule was codified as a separate *579statute. Iu Oregon Bevised Statutes the first rule of computation was with slight change codified as the current OBS 174.120. The second rule, relating to publication of notices, was codified as OBS 193.060, a part of code oh 193, relating to legal notices.
We are here only interested in determining the proper construction to be accorded to OBS 174.120 in its application to the matter at bar. It reads:
“The time within which an act is to be done, as provided in the civil procedure statutes, is computed by excluding the first day and including the last unless the last day falls upon any legal holiday or on Saturday, in which case the last day is also excluded.”
We have already noted that the defendant relies on OBS 174.120 as furnishing the governing rule for the determination of time. He also, and properly, makes a “backward” counting. Therefore, the only difference between the parties is reduced to the simple proposition of what is the proper “first day” and proper “last day” when figuring the length of time when the situation, as here, requires a backward count.
Any computation of the length of a given period of time must start from some known or established day. Such a day necessarily is the “first day” in the mathematical reckoning whether it be from that point forward or backward. The “last” day as used in OBS 174.120 is the other terminal point of a given period. We are of the opinion that the formula supplied by the statute last mentioned logically applies with equal force to the measuring of any given period of time whether the only known or established date is one which previously occurred or is, instead, a known future one.
*580In 86 CJS 856, Time § 13(5), we find the following statement:
“* * * the authorities have held that the fact that such a phrase as ‘at least’ or ‘not less than’ is prefixed to the number of days named will in no wise affect the result or the method of computation, and will not demand clear or entire days, and only mean days as counted in law, except where clear days are patently indicated. Accordingly, in computing a period of time expressed as ‘at least,’ ‘not less than,’ or ‘not later than’ the specified time ‘before,’ or ‘prior,’ or ‘previous’ to a designated day, either of the terminal days may be included and the other excluded.”
It must be remembered that ORS 255.211, supra, says “not less than 70 days before * * * the election.” [Emphasis supplied] It does not say that the filing shall be prior to 70 days before election, or that the act of filing shall be on the seventy-first day before the election; nor does it say 70 days shall intervene between election day and the filing.
If it is from some date previously occurring, such as one of the instances referred to in Beardsley v. Hill, 219 Or 440, 348 P2d 58 (decided December 23, 1959), then the calculation is made, of course, forward or prospectively from such date. If, however, as here, the only fixed date is a future one (as a date of election), then, to use a phrase from Beardsley v. Hill, supra (at 61), it is one of “the other events which precipitate or require the beginning of the computation of time.” And in that event the time period is computed backward counting consecutively or retrospectively from that date.
If we follow the mandate of the statute (ORS 174.120) in the present case and exclude the first or initial day (election day) and include the last day, *581we find that the filing attempted by the relator was tendered on the seventieth day before the election or in the statutory words: “Not less than 70 days before the * * * election,” and, therefore, in time.
The formula for the measurement which we employ in this matter has substantial support in other jurisdictions when applied under like circumstances. See State v. Lacklen, 129 Mont 243, 284 P2d 998 (1955); Barron v. Green, 13 NJ Super 483, 80 A2d 586 (1951); State ex rel Earley v. Batchelor, 15 Wash2d 149, 130 P2d 72, 74 (1942); Luedke v. Todd, 109 Colo 326, 124 P2d 932 (1942); Oliason v. Girard, 57 Ida 41, 61 P2d 288, 290 (1936); Cosgriff v. Board of Election Com’rs., 151 Cal 407, 91 P 98 (1907).
The holdings in the cases last cited commend themselves to us as establishing the correct rule when the computation of a time period must be made backward from a known future date. Each is on all fours with the facts we confront here. Each case involves the reckoning of the proper time in which to make certain filings under the election laws of the respective states. Each of the several states requires a construction of the minimum filing time under statutes which provide that the particular filing shall be made not less than a designated number of days “before the * * # election [primary or general].” Each state above named has a statute for the computation of time identical with or comparable to our OPS 174.120 and in each of the foregoing cases the court computes the period for filing in the manner that we do in the case before us; that is, excluding the election day, and counting backward for the number of days stipulated by the statute and including the last day in accordance with such reckoning.
*582Some confusion has resulted from our decisions predicated upon the rules for the computation of time as embodied in what since 1953 now are ORS 174.120 and 193.060. In 1958 the Attorney General advised the then Secretary of State to accept and file certain tendered pamphlet material and upon a time computation consistent with the one we presently approve (see Ops Atty Gen, 255 [1956-1958]). In the instant matter, he reverses the formula employed two years before. We do not say this in criticism but by way of illustrating the uncertainty he and, no doubt, many others have experienced.
The very salutary holding in Beardsley v. Hill, supra, clarifies uncertainty in the application of the formula as it is presently stated in ORS 174.120, but only in so far as it is invoked to measure periods of time predicated upon events which precipitate or require the beginning of the computation time forward from a fixed date to an undisclosed future date. But Beardsley v. Hill, supra, consistent with the factual problem then confronting the court, did not reach or rule upon the particular time computation of matters falling within the category to which this case falls; that is, when the point of reckoning is backward from a known future date to an unknown prior date to be determined by application of the formulas provided by ORS 174.120.
It is our intention by the method herein adopted and applied to allay all doubts and dissipate such confusion as may have heretofore existed as to the proper formula to follow when the situation requires a backward count from a fixed future date as the point of beginning. The result is, and we so intend, to make this opinion as supplemental to and place it in harmony with Beardsley v. Hill, supra, and thus give to *583OES 174.120 a more comprehensive construction of that section than was necessary when Beardsley was written.
To further insure that end, we overrule all cases in conflict herewith not overruled in Beardsley v. Hill, supra, and specifically State ex rel Stewart v. Macy, supra, excepting, however, such eases dealing with the rule for the computation of time for the publication of notices, as provided in OES 193.060, and its earlier counterpart, which prior to 1953 and from 1864 had been a part of all the sections which also included the rule now separately codified as OES 174.120.
If and when we are met with a problem requiring a construction of OES 193.060, it will then be time enough to clarify or harmonize, if necessary, any prior decisions of this court respecting the formula provided therein for computing time under its provisions for the publication of legal notices.
It is obvious to us that much of the uncertainty inspired by some of our earlier decisions, and particularly by State ex rel Stewart v. Macy, supra, has in large part been the product of the years when the two statutory rules for computing time were cojoined in one act and for 90 years thereafter codified together as a separate section in each of our previous codes.
State ex rel Stewart v. Macy, supra, so heavily relied upon by defendant’s counsel, offers a fair illustration. It was a proceeding in mandamus to compel the City Recorder of Salem to prepare a ballot title for a certain measure filed with him “on and between November 2, 1916, and November 4, 1916,” and cause it to be printed on the official ballot to be voted at the city’s general election on December 4, 1916. The *584election ordinance relied upon directed that initiative petitions properly signed should be filed with the City Eecorder “not later than 30 days before the next regular city election * * This court, relying on the rule found in OES 174.120 (then §531, LOL), reckoned the time precisely as did the Attorney General in this matter and sustained the demurrer to the alternative writ.
In so doing the court rested its judgment solely on two earlier cases: Rynearson v. Union County, 54 Or 181, 102 P 785 (1909), and U. S. Nat. Bank v. Shefler, 77 Or 579, 581, 143 P 51, 152 P 234 (1915). The Eynearson case was a challenge to the legal sufficiency of certain posted notices determinable by the second rule or last part of § 531, LOL (now OES 193.060), and, therefore, is not authority for a computation of time provided by the first rule of § 531, LOL (now OES 174.120). U. S. Nat. Bank v. Shefler, supra, has since been specifically overruled in the Beardsley case, supra (at 61). When thus evaluated, it fails to support the conclusions urged upon us by the Secretary of State.
The defendant in his brief also argues that Watson v. City of Salem, 84 Or 666, 164 P 567, 164 P 1184 (1917), and In re Board of Directors of North Unit Irr. Dist., 91 Or 33, 178 P 186 (1919), are controlling in this matter. But an examination of those cases reveals that both related to the calculation of time for the publication of certain legal notices in newspapers. The court in reaching its conclusion in each case made its computation, not under the rule codified as OES 174.120, but under the properly applicable rule which we now know as OES 193.060. Hence, they, too, have no value here.
By making the.method of computing time backward *585conform with the method of computing time forward as established in the Beardsley case, we think our opinion will produce desirable uniformity.
The demurrer to the alternative writ is overruled. A peremptory writ will issue.
